Breaking: #102937 - `pi1_hooks` hook removed from Indexed Search

See forge#102937

Description

Indexed Search provided the possibility to manipulate the search behavior via hooks with $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['indexed_search']['pi1_hooks'].

There are no public extensions supporting TYPO3 v12 using this hooking mechanism, therefore it has been removed without replacement. In case there are private consumers of these hooks, we will allow to add a dedicated event at appropriate places later.

Impact

If implemented, hooks in $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['indexed_search']['pi1_hooks'] are not called anymore.

Affected installations

All extensions using this hook are affected.

Migration

No migration available.
