support multiple repositories with array in crd RunnerDeployment

What would you like added?

in RunnerDeployment there is a general requirement to support multiple repository since it's more safe than organization level, but from current crd description https://github.com/actions/actions-runner-controller/blob/master/charts/actions-runner-controller/crds/actions.summerwind.dev_runnerdeployments.yaml#L3366, only string type is supported, we need to create multiple RunnerDeployment to add different repository instead of add a array in one RunnerDeployment spec.
is that ok to update repository string type to repositories array type？

Note: Feature requests to integrate vendor specific cloud tools (e.g. awscli, gcloud-sdk, azure-cli) will likely be rejected as the Runner image aims to be vendor agnostic.

Why is this needed?

Additional context

Add any other context or screenshots about the feature request here.

Start with the RunnerDeployment CRD at charts/actions-runner-controller/crds/actions.summerwind.dev_runnerdeployments.yaml around line 3366, then trace how the repository field is consumed. Determine the required schema and controller behavior for multiple repositories, and verify that a RunnerDeployment can target each requested repository without breaking existing string-based configurations.
