To Reproduce

Follow Quickstart guide(https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/quickstart-for-actions-runner-controller) with an organization named "camphor-".
githubConfigUrl is "https://github.com/camphor-".

Describe the bug

Failed to create a runner scale set. The controller log says:

"error": "AutoscalingRunnerSet.actions.github.com \"arc-runner-set\" is invalid: metadata.labels: Invalid value: \"camphor-\": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')"}

Describe the expected behavior

Create a runner scale set successfully.

Additional Context

Nothing. I just follow the quickstart guide.

FWIW, I am also hitting this issue due to my GH username ending in a hyphen. I'll try @and-es's PR and see if it's enough to resolve the issue.
