workflows: update_version.sh handles copyright year and BB files

[patrick-stephens]

Resolves #7988 and #8020 (review)

update_version.sh should now ensure the copyright date is always the current year along with fixing the Bitbake version correctly.
This script is automatically called after each release to create a PR with all the updates to the new version in. This means after each release we should get a PR with copyright and version correct.
