Follow Release Process for `3.0.0-alpha.7`

[da2ce7]

from: release_process.md

This is the second attempt. Lets see if it works.

Comments in the Develop Branch:

• The develop branch has the 3.0.0-alpha.7-develop.
• The version is bumped according to releases, new features, and breaking changes.

Process:

• develop is ready for branching for a release.
• force-push develop to staging branch.
• commit release: version 3.0.0-alpha.7, that removes the -develop suffix.
• create pull request to merge staging into main branch.
• check all status checks succeed for main branch.
• push main branch to releases/v3.0.0-alpha.7 branch.
• check all status checks success for releases/v3.0.0-alpha.7 branch.
• create signed v3.0.0-alpha.7 tag from releases/v3.0.0-alpha.7 HEAD.
• create github release from v3.0.0-alpha.7 tag.
• merge the main branch back into develop branch, assuring that the 3.0.0-alpha.7 has the suffix -develop.

Notes:

• At step 1., develop is automatically published to dockerhub.
• At step 3., main is automatically published to dockerhub.
• At step 5., releases\v3.0.0-alpha.7 is automatically published to dockerhub and crate.io.
