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.
