fix: ignore Github Actions client parameters

[rafals26]

My use case is that I use the module to create a Cloud Run instance and then a Github Actions pipeline to deploy subsequent revisions. The problem is that Github Actions deployment adds several new fields (like client_version) to the resource, which causes state drift:

  ~ resource "google_cloud_run_v2_service" "main" {
      - client                  = "gcloud" -> null
      - client_version          = "548.0.0" -> null
        id                      = "xyz"
        name                    = "xyz"
        # (35 unchanged attributes hidden)

      ~ template {
          ~ labels                           = {
              - "commit-sha"                 = "c6fafd63075cb23b53e763e427e877dd8669f999" -> null
              - "goog-terraform-provisioned" = "true" -> null
              - "managed-by"                 = "github-actions" -> null
            }
            # (9 unchanged attributes hidden)
            }

            # (1 unchanged block hidden)
        }

        # (2 unchanged blocks hidden)
    }

This small change adds lifecycle_ignore to ignore those changes. Identical code is already present in v1 resource version of the module: https://github.com/GoogleCloudPlatform/terraform-google-cloud-run/blob/main/main.tf#L191
