Subject: [PATCH] chore: enforce vX.Y.Z release tags

Calls the shared tag-format check from EduIDE/.github, so a tag push that is
not vX.Y.Z fails instead of quietly joining the three spellings this org
already has (1.1.0, v1.1.0, v.1.1.1).

The grammar lives in one place rather than being copied into each repo. Runs
only on tag pushes, so it costs nothing on a normal PR.

Depends on EduIDE/.github#3.
