Add support for multi region

[yuvalshilo]

TL;DR

It will be really helpful to use an automatic github action to deploy new revisions to multi region cloud run service.
Event tough the the tests show that it's possible to pass multiple regions (see attached image), it's not supported.
Thanks.

Hi @yuvalshilo - have you tried setting region to a comma-separated list of values? If that doesn't work, please provide the GitHub Actions debug logs.

@sethvargo I have the same need , and it's not working
The endpoint_overrides property must be an absolute URI beginning with http:// or https:// and ending with a trailing '/'. [https://europe-west1,us-central1-run.googleapis.com/

Hi there - could you please provide the debug output for the complete GitHub Actions workflow run?
