fix(tests): Use the default Playwright timeouts.

[onurtemizkan]

Resolves: #6848
Resolves: #6872

Updating Playwright configurations to use the default 30 seconds, instead of 12 seconds configured. Not sure why we decreased the test timeout in the first place.

The case in #6848 happens randomly in any test in the same file, so I suspect this is just about the shortened timeout, rather than certain implementation / test that trigger flaking.

Testing here to check if there is a hanging test that hits the default 30 seconds.

Edit: No flakes for #6848 or #6872 after 9 CI trials on this PR.
