Added container and usage info about modules in this PR: #7826

[ppf2]

@dedemorton Just to confirm.

Does this item

Two links for plugin version navigation: master and latest compatible version

represent a new documentation set that will map out compatible plugin versions (for all supported plugins) <-> LS core version? If so, this is 🍾 🎆 ❤️ :)

[acchen97]

Updated with 6.0 GA outstanding issues.

@ppf2 we plan to resolve this with a compatibility statement in the LS plugins support matrix. Now with LS 2.3 and prior EOL, all the newer plugin versions should work on all LS 2.4+.

[dedemorton]

@ppf2 We do also want to make plugin docs available in multiple versions, but that's going to require some dev cycles to work on our tooling...just haven't had the time yet.

Closing out doc meta issue from 6.0. Any remaining items from the backlog and other lists have been moved to #8683
