[EDR Workflows][Osquery] Increase initial page load timeout, unskip t…

…ests (elastic#190231)

This test failed in the `before` block because the page did not load
within the expected default of 60 seconds. Since Serverless (where the
test failed) can be slower at times, I've increased the timeout to 90
seconds, as we have no control over the app's loading speed.
