This is a follow up from https://gitlab.com/gitlab-org/gitlab/-/merge_requests/34634. The default job name for [Browser Performance Testing](https://docs.gitlab.com/ee/user/project/merge_requests/browser_performance_testing.html) is currently named just `performance` in it's [template](https://gitlab.com/gitlab-org/gitlab/-/blob/master/lib/gitlab/ci/templates/Verify/Browser-Performance.gitlab-ci.yml). After several attempts in the MR to change it to the intended `browser_performance` it was concluded to not be feasible currently to do this as well as maintain backwards compatibility with users who are using the `performance` job currently. In addition to this we should also update the `PERFORMANCE_DISABLED` [AutoDevOps environment variable](https://docs.gitlab.com/ee/topics/autodevops/customize.html#disable-jobs) to `BROWSER_PERFORMANCE_DISABLED`. As such, we'll look to do this later as a breaking change making sure to notify users with enough time.
