Remove stale usage quotas entry from browser console allowlist

Master is failing spec/support_specs/browser_console_allowlist_spec.rb ("scopes to spec files that exist"). 0292b66e migrated the Usage Quotas feature spec to MSW and deleted ee/spec/features/profiles/usage_quotas/usage_quotas_spec.rb, but spec/support/browser_console_allowlist.yml still lists it.

This removes that one stale path. The replacement is a Jest integration spec, so the browser console allowlist does not apply to it. The PipelineUsageApp entry stays for ee/spec/features/ci/ci_minutes_spec.rb.

Failing spec: spec/support_specs/browser_console_allowlist_spec.rb
