fix: attach git credentials before Tag Major Version push

The Tag Major Version step ran 'git push origin' after Checkout Again
re-cloned with persist-credentials: false, leaving the remote without
credentials. This caused 'fatal: could not read Username' (exit 128) on
the first release. Set the authenticated remote URL using OSDS_ACCESS_TOKEN
before pushing tags, mirroring the Update README step.

-#### Immutable subject claims
-
-Repositories created on github.com on or after 15 July 2026, and older
-repositories that have opted in, emit an [immutable `sub` claim][immutable-sub].
-This claim appends the permanent numeric ID of the organization and of the
-repository after each name, separated by `@`, so that a recycled org or
-repository name cannot be used to mint tokens matching a stale trust policy.
-For example:
-
-```text
-# Legacy (mutable) sub claim
-repo:octo-org/octo-repo:ref:refs/heads/main
-
-# Immutable sub claim
-repo:octo-org@123456/octo-repo@789012:ref:refs/heads/main
-```
-
-If your trust policy matches the legacy name-only form and your repository emits
-the immutable claim, `AssumeRoleWithWebIdentity` fails with `Not authorized to
-perform sts:AssumeRoleWithWebIdentity`. To fix this, update the `sub` condition
-to the immutable form. You can find your repository's prefix in the Settings,
-or by following the token inspection steps below.
