feat(cloud): markdown: do not parse or render images in cloud envs

[hoorayimhelping]

Closes idpe 5288

• Creates a cloud-aware markdown renderer that behaves as it always has on OSS, but blocks image loading on cloud.
• Refactored existing Markdown component to use the new MarkdownRender and to be renamed ScrollableMarkdown (it's wrapped in a DapperScrollbar) to avoid future confusion.
• Made all other instances of markdown rendering use the new cloud aware renderer

Cloud behavior:

• In editor window, show warning: We don't support images in markdown for security purposes
• In note, show literal markdown string

OSS Behavior:

• Render the image normally

Testing Instructions

1. In an OSS Context:
2. Go to a dashboard
3. Click add note
4. In the text editor add a markdown image ![](url.to.image/image.jpg)
5. it should render in the preview
6. Click save
7. It should Shown below the cell.

---

1. For a cloud context, change this line to if (CLOUD || true)
2. Reload the dashboard you just edited
3. The note you added should show the literal image markdown
4. In the top right corner of the note, click the gear and click Edit Note
5. You should see a warning saying we can't render markdown for security reasons
6. add another markdown image ![](url.image) to test parsing new text - the same warning should pop up
