chore(deps): update Terraform `google` provider to `>= v5`

See merge request !23

For terraform modules we generally should only ever specify *minimum*
versions. From the docs[1]:

> Reusable modules should constrain only their minimum allowed versions
> of Terraform and providers, such as >= 0.12.0. This helps avoid known
> incompatibilities, while allowing the user of the module flexibility
> to upgrade to newer versions of Terraform without altering the module.

fix: ignore changes to docker repository

See merge request !14

Cloud Functions creates a docker repository for us when the function is
created. It's non-trivial to get that name but ignore changes to the
`docker_repository` argument so that we don't get a perma-diff.
