Conventional Release fails when repo has no tags

[BFisch14]

When setting up a fresh repo and adding the Conventional Release action into a workflow, the pipeline fails with
fatal: No names found, cannot describe anything. Error: Process completed with exit code 128.
Which isn't the most helpful error message, I believe the issue stems from this step in the entrypoint script https://github.com/liatrio/github-actions/blob/master/conventional-release/entrypoint.sh#L19 where we try to describe the current tags of the repo.
