* Remove mention of no longer used IRC network
Channels exist on matrix, and on libera.chat now.

The current search would match files such as 'createpng'.

The result was always false, due to comparing a literal string instead of a variable.
* Use correct license files from upstream
Correct license files obtained from:
https://www.gnu.org/licenses/old-licenses/gpl-2.0.txthttps://www.gnu.org/licenses/gpl-3.0.txthttps://www.gnu.org/licenses/old-licenses/lgpl-2.1.txthttps://www.gnu.org/licenses/lgpl-3.0.txt

This fixes several shellcheck warnings, as well as makes the code more
robust and have consistent codestyle between all the files.

is also used)

* Add help text how to find KeePassXC version [skip ci]
