Feature: #93591 - Allow group id lookup in conditions with array operator¶

See forge#93591

Description¶

In the backend and frontend the array of user group ids of the current backend user is now available as backend.user.userGroupIds.

In the frontend the array of user group ids of the current frontend user is available as frontend.user.userGroupIds.

Impact¶

This allows for a native Symfony Expression Syntax in TypoScript conditions, e.g.

[4 in frontend.user.userGroupIds]

[2 in backend.user.userGroupIds]

Copied!

With this syntax you can match backend user groups in the frontend without a "like" expression on the comma-separated list of user group ids.
