Summary:
Closes #1719

This issue has 2 parts:

• Include automated Github action of Notice Migration updates when the release is official

The new process is:

1. Manually run the notice migration GH action (manually specifying the version) -> this adds to the NOTICE_MIGRATION.md file and creates the PR
2. Merge the PR
3. Release

• Upload the .zip installers to the release assets.

Expected behavior:
Follow the new section 2. Update NOTICE_MIGRATION.md file in docs/RELEASE.md.
After running the github action, a new PR should have been created with the notice migration data for the specified release.

For the upload zip installers task , create a fake draft release and verify that the 3 installer zip files are present as release artefacts.
