Update wait for Product Analytics set up button for onboarding test
What does this MR do and why?
Update wait for Product Analytics setup button for Product Analytics onboarding test. Previous wait implementation was not working properly in CI as when button is not present `find_element` would fail and abort the test.
The failure was occurring only when running in CI, when the test was executed against local GDK it was passing just fine.
