Add more detailed documentation of bs decorators

[smorimoto]

Right now, there's a section that lists them, but information about how to use them is scattered in quite a few places, turning them into hidden knowledge. This will definitely confuse beginners and make them want to go back to their former community.

[smorimoto]

Here is the list: https://rescript-lang.org/docs/manual/latest/interop-cheatsheet#list-of-bs-decorators

[smorimoto]

Oh, the old version seems to be still here: https://rescript-lang.org/docs/reason-compiler/latest/decorators
If you are looking for such a document, it's recommended to look here for the time being.

We will revisit this document in a new revised, and easier to navigate version in the future

[smorimoto]

That's pretty good. After all, these are the most important part of JavaScript interop, and the fact that documentation about them is still hidden or scattered is a major downside.

Will be fixed by #111

Almost all decorators should now be documented in our current Syntax Lookup Widget page:
https://rescript-lang.org/syntax-lookup

Let me know if this is solving your issue, and let us know if you miss any particular decorator.

Will close this for now. Open any new issues if there's anything important missing!
