feat: add a migration script to update common-ci-tasks

This updates common-ci-tasks, before migrating to components. We need
this because we broke updates to `common-ci-tasks` in the past,
leaving some projects behind. We fixed this in v2.52.2

This manually updates them, as updating common-template-copier does
seem to work. For example in
https://gitlab.com/gitlab-com/gl-infra/capacity-planning-trackers/gitlab-com/-/merge_requests/376/diffs

Tried this script locally:

```
(main ✓) gitlab-dedicated-staging /Users/bvl/repos/gitlab.com/gitlab-com/gl-infra/common-template-copier/migration-scripts/update-broken-common-ci-tasks-version.py
(main U:1 ✗) gitlab-dedicated-staging git diff
diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml

But it does not do anything for projects that are already on the
renovate train, and have a version newer than 2.52.2.
