Update docs buttons/versions to reflect that we've staged the 1.26 release

[trivial/rote, not reviewed]

This is the usual update to the docs button version numbers to distinguish
1.25 from 1.26 from main (1.27 pre-release) which we do between snapshotting
the docs for 1.26 (earlier today on chapel-www) and cutting the release.
