chore: emui enable cypress retries (#2081)

## Description:
@leoporoli has identified a case of the cypress tests again failing due
to a flakey test, subsequent to the attempt to fix in #2068.

Related failed runs are:

These jobs have both failed in the `Can create and update an enclave`
test, which is the most important ete one for the emui. On subsquent
retries @leoporoli was able to have the test succeed.

It's not clear to me what is causing this flakiness, so this pr makes
two changes:
* Increase some hardcoded timeouts which post #2068 are actually less
generous than the default (I think this may have been the issue on the
second failure)
* Allow up to 3 attempts on a test when running in CI.

## Is this change user facing?
NO
