Fix link checker not creating issues

Due to hidden change of how exit code is handled in https://github.com/lycheeverse/lychee-action/releases/tag/v2.0.0

Don't write 3 sentences about what has changed in the context of X; simply write:
* Replace ``env.lychee_exit_code`` with ``steps.lychee.outputs.exit_code``

like you somehow did on the Readme?
