fix: flaky anti-pattern getText + assert 2

[seaona]

Description

Continuing the work of removing the e2e anti-pattern of finding the element and then asserting its text.
There are more occurrences, but this work is split in several PRs, for an easy review and a faster ci.
Once all occurrences have been fixed, we'll be able to merge @HowardBraham 's PR for adding a lint rule which prevents introducing it again.
