Feature: #77349 - Additional locations for extension icons
See forge#77349
Description
Extensions can now hold their extension icons in additional locations to the existing ones (ext_icon.png, ext_icon.svg, ext_icon.gif):
Resources/Public/ Icons/ Extension. png Resources/Public/ Icons/ Extension. svg Resources/Public/ Icons/ Extension. gif
This makes it possible to restrict access to more directories, thus hardening the TYPO3 instance.
