Use stricter text selector on test (#50848)

* Use stricter text selector

Removes text ambiguity to avoid errors like "Strict mode violation resolved to 2 elements". For instance, it might search for "Settings", and there might be a menu "Foo Settings" which would resolve to 2 elements. This changes the behavior to match the exact test, instead of a substring.

* Update page-loads.spec.js

* Add changefile(s) from automation for the following project(s): woocommerce
