Fix cutting off action menu items in overview video table

[ferishili]

This PR fixes #261

How it works:

• in recent versions of Moodle there is a div with no-overflow class before any flexible table rendered, by this PR we will override the behavior of that div!

To test:

• Latest version of tool_opencast
• Make sure you have purged all the caches after installing this patch

NOTE: Please follow the comments below (https://github.com/Opencast-Moodle/moodle-block_opencast/pull/339#issuecomment-1649797818)

This problem is in fact a known bug in Moodle, following this: MDL-77375

That means, the initial fix commits of this PR are no longer needed. And since the affected Moodle versions are (4.0.6, 4.1.1, 4.1.2, 4.1.3, 4.2 regressions, 4.2, 4.2.1, 4.2.2), one must upgrade his/her Moodle to 4.1.5, 4.2.2 which at the time of writing this are not yet released!

What is left to do from our side is to only use set_boundary function when creating action menus! And hope everyone sees this PR and gets informed about this MOODLE BUG (not block_opencast!) That they need to upgrade their moodle to above-mentioned-fixed versions and not creating issues reporting a bug related to this repository!

For Info: the fixed moodle releases (4.1.5 & 4.2.2) are now (as of writing this) available!
