Increase Capybara's timeout
EE MR: https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/1552
What does this MR do?
Increase Capybara's timeout on the CI.
I've also:
- Disabled assets warming for Capybara/RSpec on the CI
- Removed a check to skip assets warming when
./tmp/cache/assets/test
exists because assets are now served bywebpack-dev-server
(./tmp/cache/assets/test
is never populated).
Closes #30236 (closed)
