Update:

• Merged with V5.0.6 #3069 it's now about finding the right text for this pill.

Initial description:

• Add "First release" pill for vX.0.0 and first release of an LTS Update (so "New feature" can continue to be used for a relevant feature addition to an existing package)
• Add compatible editions to LTS Update entries when missing
• Add version number when missing
• Filter right side bar ToC as well

There are some possible improvements but not sure they worth it.

Really like the idea, I'd just call it "initial release" instead of "first release"
