Major rework of ecosystem pages

[svrnm]

This PR addresses some of the things we discussed in #2178, #2238, #1701

Note, that I made a lot of decisions along the way, so don't hesitate to call out anything you dislike on how I have changed things.

Here are a few pointers:

• All three pages (vendors, adopters, integrations) are data-driven. I am not yet 100% satisfied with the format, but I think it's a starting point
• There are short codes to render tables from those.
• I updated the vendors table to also mention if there are open source offerings or if the offering is maybe even purely OSS (jaeger, skywalking, etc.), it makes the name "vendor" a little bit odd, but I think we can discuss this
• The vendors are now listed pure-oss-first, oss&commercial second, only commercial last and then alphabetical within, I felt that this is the best order as it highlights OSS offerings
• I added a footnote to every page what is required to be added to the list. As you maybe can see they are stricter than before (provide a contact, provide proof for everything). I also added a note that exempts existing entries until Jan 1th next year.
• For "adopters" and "vendors" there should be a contact, as they mostly come from those organisations. For integrations I did not add this requirement as they have been added by ppl from the otel community.
• I removed the "within opentelemetry" integrations list, I found that one really odd, as it just lists some projects but gives no indication how those are integrated (my assumption is that for all of these there are collector exporters/receivers or maybe language specific exporters/receivers, this is represented through the registry)
• After we have this in place I can crawl previous PRs to find existing contacts for adopters & vendors, such that we can alert them to review their entries.

I really like the changes overall. I think the vendors table needs some CSS work to widen it, though. Compare what's changed here:

With what's live:

[cartermp]

Hmmm, I guess now that I lay it out it's not that much worse. Eh, let's deal with that later.

Love the changes overall.

Would also like @chalin to pipe in here, but otherwise I think this one's good.

Taking a look now (just back).

Oh, very nice improvements; thanks @svrnm! 🎉

I focused on copyedits for the prose in this round of reviews. See inline comments.

(Later I might have some suggested improvements and simplifications to offer for the shortcodes, but they could land as is for now too.)

[svrnm]

thanks @chalin , I applied all the suggestions you made

[chalin]

Getting there! I made another pass of copyediting. PTAL

thanks once again, all suggestions have been applied

Thanks @svrnm.

Maybe try the /fix:* commands (for fix:format and fix:refcache) to see if they work?

[svrnm]

/fix:*

[chalin]

Sorry if I wasn't clear: I meant to try each command separately. We don't have /fix:* enabled yet -- I used that syntax to avoid triggering the scripts :)

[chalin]

All green, merging!
