Update lints ahead of #1462, so that #1462's diff is smaller

[NullVoxPopuli]

Extracts lint dependency updates from #1462 to reduce #1462's diff.

This may cause conflicts, but they'd only be in the package.jsons or lockfile.

Also, notes were added to the .eslintrc.cjs' that would re-enable lints that are known to be fixed in #1462, as the updated lint dependencies made some things more strict.

Something I noticed is that there is a difference in expected behavior with
lints, and turbo's usage in this repo.

mainly every way of doing:

pnpm turbo test:lint --filter @glimmer/syntax

(for any package)
fails without eslint being in each package.json

So eslint has been added to every package.

Also, due to: actions/setup-node#865

I've forced node 20 in ci
