[Backport release-25.05] go_1_25: init at 1.25.1

[mdaniels5757]

Manual backport of #420392 #431616 #433239 #441005 to release-25.05.

I don't touch go, buildGoModule, go_latest, or buildGoLatestModule, and without removing old versions because both of these would be breaking changes.

The nixpkgs-vet failure is expected: the check failed on master as well.

The cherry-pick failure is expected too due to the nixfmt 1.0.0 treewide.

Just a formatting change
