fix: reference index update no longer fails on the job application forms

referenceindex:update stopped at tt_content with "The Prototype
applicationform was not found": the backend and the CLI (form editor,
FlexForm of the form plugin, reference index) read module.tx_form, and the
form setup was only registered for the frontend (plugin.tx_form). TYPO3 10
set module.tx_form in the site TypoScript; TYPO3 13 reads it only from
global TypoScript, so ext_localconf.php registers FormSetup.yaml there.
