DEV: Speed up slow system tests (#21803)

What is the problem?

Prior to this change, we had a `has_css?(context + ":not(.is-expanded)"`
check when using the select-kit component page object. The problem here
is that this check will end up waiting the full capybara default wait
time if the select-kit has already been expanded. It turns out that we
were calling this check alot of times when the select-kit has already
been expanded resulting in many tests waiting the full default wait
time.

What is the fix?

The fix here is to specify the `wait: 0` option such that we do not wait
and fundamentally, there is no need for us to wait at all here.
