add timeouts for tests (#7657)

* install `pytest-timeout` into all environments

* don't also install it into the upstream-dev environment

* set a timeout of 5 minutes

This is plenty for a test to run: we shouldn't have tests that take
more than 30 seconds, but the windows / macos runners tend to be
slower than the linux ones.

* add `pytest-timeout` to the remaining test environments

* add `pytest-timeout` to the ignored dependencies [skip-rtd]

* reduce the timeout from 5 minutes to 90 seconds

* double the test timeout
