[meta] 11.0.0 milestone release notes

The release notes for the 11.0.0 pre-release milestones (alpha, beta, etc.) are all subtasks of creating the 11.0.0 release notes, because we compile the alpha, beta, etc. notes together to make the final release notes for the minor. So retitling back.

Crediting additional sponsor.

Clarifying title that this is the meta, since I thought for a second we had a dupe.
