Add a step to add a link to the newly cut branch in [cut-release-branch.yml](https://github.com/dbt-labs/actions/blob/4a9bc4a86549ced8afb9b1cdca6aedb64f38154c/.github/workflows/cut-release-branch.yml#L243) to [Previous Releases](https://github.com/dbt-labs/dbt-core/blob/main/CHANGELOG.md#previous-releases) in the `CHANGELOG.md`. Could be done with some simple bash scripting. ### Problems this would solve - https://github.com/dbt-labs/dbt-core/pull/10082 - https://github.com/dbt-labs/dbt-core/pull/8886 - https://github.com/dbt-labs/dbt-core/issues/7671
