Update workflow configurations for changelog and release

The `.github/workflows/update-changelog.yml` workflow is now checking out from the `v3` branch instead of `main`. Additionally, `.github/workflows/release.yml` workflow now supports manual triggering with `workflow_dispatch` event and the automatic release tag is now set using the current date and commit SHA.
