Update webservices-infra and global-platform-admin for spanner image

[data-sync-user]

Since we now have both spanner and postgres builds in GAR and GHCR we will need to scope what we deploy given the database suffix. Since the images have suffixes pointing to the specific build, we may consider updating this.

The two places we need to make adjustments (thanks to JBUCKfor confirming) are:
https://github.com/mozilla/global-platform-admin/blob/main/tenants/sync.yaml
https://github.com/mozilla/webservices-infra/blob/main/sync/k8s/sync/values.yaml#L39

Set image_regex: <sha 10>--<timestamp> for each Argo application and then toggle auto sync on or off for different environments. We want to make sure to update all of the image_regex values here.
