Improve README readability

[ggrossetie]

📑 Summary

Improve the readability of the README:

• Fix link to the changelog
• Remove changelog from the readme
• Use titles sparingly
• Add emojis! 🎉

📏 Design Decisions

In my opinion, the README is hard to parse because there are too many bold paragraphs and titles.

📋 Tasks

Make sure you

• 📖 have read the contribution guidelines
• 💻 have added unit/e2e tests (not applicable)
• 🔖 targeted develop branch

Thanks @NeilCuzon!

I would like to improve the documentation, published at https://mermaid-js.github.io/mermaid, but I'm not sure where the content is stored.
I found several "copies" of the documentation:

• https://github.com/mermaidjs/mermaidjs.github.io
• https://github.com/mermaid-js/mermaid/tree/develop/docs
• https://github.com/mermaid-js/mermaid-js.github.io
• https://github.com/mermaid-js/docs
• https://github.com/mermaidjs/mermaidjs.github.io
• https://github.com/mermaidjs/mermaid-gitbook

I would recommend to archive deprecated repositories to make it easier to contribute documentation.

the content on display here: https://mermaid-js.github.io/mermaid, are auto-generated from the docs in the master branch.
it does have some sister projects and those could be the other repositories in the project.

there is a shortage of hands at the moment, your help would be very much welcome.

your earlier contribution was in the right place actually, @knsv is generally the one who merges the develop and master branches when there is a new version for release.

if you would like, you can make some edits to the docs here: https://github.com/mermaid-js/mermaid/tree/develop/docs
