feat: Update build/release workflows

[spalmurray]

Updates build and release workflows to work with new package structure and repo.

Notable changes:

• We're moving from our codecov-releaser bot account to the recommended Sentry Release Bot GitHub App.
• I've removed the commit signing step from the release PR creation flow as it seems we probably don't care enough to do the extra work needed to set this up based on this workflow in the main monorepo.

I have tested all workflows with the exception of release_flow.yml as it needs secrets we don't yet have (working on it).

Next PR will add the build steps for prevent-cli, this one is only getting codecov-cli to work.

After this is merged, we should be able to start publishing codecov-cli from this repo exclusively.
