Pin every action reference to the full commit SHA that its current tag
already resolves to, with the version kept in a trailing comment. No action
changes version as a result of this commit -- including actions/setup-node
in validate_issue.yml, which stays on v4.4.0 rather than being lifted to the
v6 used by the other workflows. Version bumps are left to Dependabot so they
arrive as reviewable PRs.
Add .github/dependabot.yml for the github-actions ecosystem: weekly on
Monday, minor/patch grouped into a single PR (majors always get their own),
"ci" commit prefix. tibdex/github-app-token is ignored to match
iptv-org-database; it is archived upstream, so replacing it should be a
considered migration rather than an automated bump.
