Build requirements out of date

Bug report checklist

• [ ] Always send the vokoscreenNG log, after a "Start" and "Stop" - irrelevant, this is about building
• [x] Have you searched the existing issues to see if this report is a duplicate?
• [x] Are you using the latest version of vokoscreenNG? (from git, 4.0.0 tag checked out)
• [x] Are you familiar with https://www.mediawiki.org/wiki/How_to_report_a_bug ?

Describe the bug

Hi - as apparently, there's no longer a build for Linux anymore for release 4.0.0, I wanted to build vokoscreenNG myself now (or had to, rather).

Trying to follow the build instructions for Linux here: https://github.com/vkohaupt/vokoscreenNG/blob/3.0/.github/README.md , I've encountered different requirements, namely qt6 instead of qt5.

qmake complains:

Project MESSAGE: Cannot use Qt 5.15.3
Project ERROR: Need minimum Qt 6.5

Expected behavior

Following the instructions, I should be able to build the project.

(turns out, though, that Ubuntu 22.04 is no longer supported anyway, as the latest QT version available for me here is 6.2.4, so I won't be able to build anyway. Also means I couldn't test whether other requirements were outdated, as I never got so far in the process as to have it complain eventually).

Due to Ubuntu bugs, it would be helpful to write 'qmake6' instead of 'qmake' only, because choosing the version doesn't work properly, even if installed.

Thanks for the hint. Build requirements have been revised.

@vkohaupt Almost - there's still the 'On Ubuntu these requirements can be satisfied by running sudo apt install libgstreamer1.0-dev qt5-default qttools5-dev-tools libqt5x11extras5-dev qtmultimedia5-dev libqt5multimedia5-plugins libpulse-dev libwayland-dev' with lots of Qt 5s in it.

[vkohaupt]

I deleted it because it's not applicable at the moment.

Might be for newer Ubuntus, didn't check - but it's fine, thank you!
