[Usage Collection] MDX documentation

[afharo]

Let's improve the documentation by converting https://github.com/elastic/kibana/blob/master/src/plugins/usage_collection/README.md to MDX.

Also, let's create some example plugins using the collection APIs to showcase them and how they should be used.

Let's create another issue for the examples :)

@afharo what usage collection APIs do you want to showcase and should we add a new example plugin for each of them?
Maybe we can group the usage collectors we decide to use into an example (maybe a server-side and client side collector) and then add some sort of a minimal UI to show the data itself.

[afharo]

I think the examples should show how each of the APIs exposed by the Usage Collection service work.

Maybe it can be just 1 example plugin making use of all of them (properly commenting the code to explain them?). What do you think? Would it be too messy?

@afharo I've added a new issue for adding example(s). We can chat about the design and what we want to showcase in there.
Examples are an enhancement so there's no real rush for that. We can start small and iterate on that.

@TinaHeiligers do you think we can close this issue? It looks like the PR converting the README to .mdx was merged :)

The conversion to .mdx only partially addressed this issue request. We still need to add examples.

AFAIK, we've got #92668 to track the examples effort. Does it make sense if we update the title to remove the + examples bit and close it?
