8.3.0 API updates

[paul-griffith]

Did a bunch of dependency updates at the same time, mostly a YOLO but some quick consideration suggests they should be safe.

I'd love to have you review this @benmusson if you've got time - otherwise I'll merge it in just to get a proper build going and let folks who are asking for it beta test.

[paul-griffith]

My local environment is very unhappy with me and I haven't been able to un-break it but pushing some test commits to see if it'll build on CI at least

[benmusson]

Actually same.
I tried to make a PR last night, ran into the exact same issues with compiling test classes, and gave up.

I couldn't figure out why the test classes are still trying to compile against 2.1.20's standard library.

[paul-griffith]

Yeah... huh. All right, well at least it's not just me. Maybe it's something implicit from kotest...

[paul-griffith]

Well, that's a very unfortunate failure mode.
TODOs for myself:

1. Use a build convention plugin or whatever they're called to DRY up the toolchain stuff
2. Update the renovate config file to exclude the test libs from automatic dependency updates as long as we're sticking to Kotlin 1.9 in Ignition (hopefully changing soon 🤞)

1. build convention plugin

I like using a composite build, like includeBuild("build-logic"), instead of relying on buildSrc.

buildSrc = magic
includeBuild("build-logic") = explicit

For a project of this size it doesn't really matter though.
