[TASK] Check existence of div.module only

Due to issue https://forge.typo3.org/issues/91127 the module "Help >
About" can't be the default anymore, thus the acceptance tests must not
rely on this.

As a replacement, we check whether `div.module` can be found, which
should be sufficient for the intended check.
