Bump integration image versions automatically during release

[jangel97]

Context

From PR #145 discussion — integration files (integrations/gitlab-ci/claudio.yml, integrations/tekton/claudio.yml) currently have a pinned image version that needs to be bumped manually on each release.

Proposal

Add a step to the release workflow (.github/workflows/release.yml) that after creating the GitHub release:

1. Updates the image version in both integration files using sed
2. Commits and pushes to main

This keeps integration images in sync with releases automatically.
