Fix microsite compile

[rpless]

Our microsite build has been broken and outdated while we've been moving to an Effect Agnostic Endpoint. This PR fixes the sbt docs/makeMicrosite command. The code examples in the docs all compile but the text that surrounds them is still out of date. My current thinking is that we can use this as a base to fix the text, although I'm open to alternative approaches to fixing our docs. If we decide to merge this, I don't think we should publish the docs to the website until all the text has been fixed.

Some things to note / questions:

• I replaced the Server Sent Event example's use of AsyncStream with Fs2
• The latest sbt-microsites seems to replace favicons and icons with its own. I've noticed this on other microsites like cats effect.
• Set the docs compilation tool to Tut, but we should probably consider moving to mdoc in the future
• contributing.md probably needs to get updated to no longer mention Waffle which no longer exists

That's great!

Thanks a lot @rpless

What I did in Odin is to compile docs on each PR, so it becomes a part of the check, as well as automatically compile and publish documentation back on GitHub during release. I guess we might onboard similar mechanism here to avoid severe discrepancy between documentation and actual code.

I like the sound of publishing on release. It might also be related to #1002. I'm going to merge this and will look at more fixes so we can get ready for a release.
