I understand that GCR is being redirected to GAR, but eventually the GCR repos will be fully deprecated, and so it would make sense to me to have Leo explicitly pull from GAR

See https://github.com/DataBiosphere/leonardo/pull/4372/files

[lucymcnatt]

We can discuss it more, but this is Leo pulling from GAR, on the cloud console it specifically says that:

All "*gcr.io" traffic is routed to Artifact Registry.

The paths are all the same so maybe I'm missing something but I don't see how adding a different regex for GAR makes a difference?

[LizBaldo]

Gotcha, I did not realize the paths were similar since they contained gcr in the string 🤔 In that case I don't know why the Sfkit folks wanted to do that.
