fix(ci): fix publishing and codecov workflow failures

- Remove bare `push:` trigger from release workflows that caused them
  to run on every push to every branch (they still run via workflow_run
  on main and on release events)
- Add `force: true` to flutter publisher to avoid dependency resolution
  failures during dry runs
- Replace deprecated codecov uploader script with codecov/codecov-action@v4
