What

Automate steps 1 - 8 of "Publish a new version of GOV.UK Frontend".

The first step should be the trigger of the build (likely through a GitHub workflow_dispatch action), and the final step should be the creation of the PR. PR review will be done manually.

Why

The current release process is done locally on a developers' machine, which presents security risks and means we don't have a controlled release environment. It can also take a long time, and require folks to wait around while we work through the steps.

Developers

Done when

• A way to trigger the workflow has been decided
• We have a Github workflow that automatically runs the existing manual steps
• [Potentially another issue] We have a way to automatically finesse the CHANGELOG
• We have the means (probably some tests) to validate that the build has successfully completed and doesn't look weird
• We have updated the documentation for this step
