Doc updates for overlay resources

[EronWright]

Proposed changes

Some minor updates to the API docs for the overlay components:

• link to the newer version of the respective component, since the newer versions have fixes for some of the long-standing issues with these overlays.
• clarify the supported languages

I had considered adding a "known issues" section, e.g. to mention the dependsOn limitation, but I felt it would be overkill, and that simply linking to the newer version would suffice.

Closes #1773
Closes #2181
