Add CC-25M announcement to docs (#468)

This PR adds the CC-25M announcement to the docs website in two parts:

- The tech community announcement, which can be reached both from an
announcement banner at the top of the page, and the navigation bar on
the left.
- The press release, which is available by its url directly, but not
linked from the docs site.

+# 25 million Creative Commons image dataset released
+
+[Fondant](https://fondant.ai) is an open-source project that aims to simplify and speed up 
+large-scale data processing by making containerized components reusable across pipelines & 
+execution environments, shared within the community.
+
+A current challenge for generative AI is compliance with copyright laws. For this reason, 
+Fondant has developed a data-processing pipeline to create a 500-million dataset of Creative 
+Commons images to train a latent diffusion image generation model that respects copyright. Today,
+as a first step, we are releasing a 25-million sample dataset and invite the open source 
+community to collaborate on further refinement steps.
+
+Fondant offers tools to download, explore and process the data. The current example pipeline 
+includes a component for downloading the urls, a simple file type filter, one for downloading 
+the images and one for deduplicating the urls. Additional processing components which could be 
+contributed include, in order of priority:
+
+* Image-based deduplication
+* Visual quality / aesthetic quality estimation
+* Watermark detection
+* Not safe for work (NSFW) content detection
+* Face detection
+* Personal Identifiable Information (PII) detection
+* Text detection
+* AI generated image detection
+* Any components that you propose to develop
+
+The Fondant team also invites contributors to the core framework and is looking for feedback on 
+the framework’s usability and for suggestions for improvement. Contact us at 
+[[email protected]](mailto:[email protected]) and/or join our [discord](https://discord.gg/HnTdWhydGp).

+# 25 million Creative Commons image dataset released
+
+> Fondant is an open-source project that aims to enable compliant, large-scale processing in a
+> simple and cost-efficient way. As a first step, we have developed a pipeline to create a  Creative Commons image dataset and are releasing a first 25 million sample with a call to action to help develop additional data processing pipelines.
+
+[Fondant](https://fondant.ai) simplifies and speeds up large-scale data processing by making
+self-contained pipeline components reusable across pipelines, infrastructures and shareable
+within the community. By offering a library of ready-to-use, off-the-shelf components and a
+standardized way of building and combining them with custom components, it significantly reduces
+the time required to build and maintain data processing infrastructure for generative AI
+applications in production.
+
+Supported by [Flanders innovation & entrepreneurship](https://vlaio.be) and European AI Service
+Provider [ML6](https://ml6.eu), Fondant developed a pipeline to create a
+[dataset](https://huggingface.co/datasets/fondantai/fondant-cc-25m) of over 500 million Creative
+Commons-licensed images from Common Crawl to train an image-generation model that respects
+copyright. Now we are releasing a first 25 million sample dataset with tools to download,
+explore and process the data. We are inviting developers and data enthusiasts to collaborate on
+large-scale data processing pipelines by building custom components for advanced filtering and
+captioning and to contribute to the core framework. We are also looking for feedback on the
+framework’s usability with suggestions for improvement. Contact us at
+[[email protected]](mailto:[email protected]) and/or join our [discord](https://discord.gg/HnTdWhydGp)
+to help realize this vision.

 For demonstration purposes, we provide sample pipelines in the Fondant GitHub repository. A great starting point is the pipeline that loads and filters creative commons images. To follow along with the upcoming instructions, you can clone the [repository](https://github.com/ml6team/fondant) and navigate to the `examples/pipelines/filter-cc-25m` folder.
