tests: increase timeout for OperatorHub subscription form

[spadgett]

Increase the timeout in an effort to address the following flakes. I suspect this is happening because icons might still be loading in the background, which makes the form slow to load (even with lazy icon loading).

It looks like the timeout is either happening for checkLogs or checkErrors in afterEach, not waiting for the subscribe button, so the timeout increase here hasn't addressed the flake.
