Improve `xdg-desktop-portals` processes termination since
`xdg-desktop-portals` is 19 characters long.
From `killall(1)` man page:
> -e, --exact
>
> Require an exact match for very long names. If a command name is longer
> than 15 characters, the full name may be unavailable (i.e. it is swapped
> out). In this case, `killall` will kill everything that matches within
> the first 15 characters. With -e, such entries are skipped. `killall`
> prints a message for each skipped entry if -v is specified in addition
> to -e.
XDPH doesn't need ** keyword, it means portage will pull in the latest git version of XDPH available, which at the time of writing the wiki may have been required, but is not necessary now.
* Update Gentoo installation instructions for XDPH
* Changed the suggested overlay from useless-overlay to GURU.
* Bumped qt versions in the docs from 6.4.0 to 6.4.3 since 6.4.0 is not available anymore.
* Remove dependency on specific Qt versions for the Gentoo instructions
Now, the instructions suggest to just unmask the whole package instead of specific versions.
* Added wl-clip-pesists to the clipboard manager list
Normally, when we copy something on Wayland and then close the application we copied from, the copied data (e.g. text) disappears and we cannot paste it anymore. It is very frustrating when I copy something from a clipboard and the copied data disappears after I close the application. It effects peoples work flow. So we can use something called as wl-clip-persists (https://github.com/Linus789/wl-clip-persist) which will preserve the data in the clipboard even after the application from where we copied the data is closed.
* Edit #2
minor fixes
* Added an example to the special workspace section
Special workspace section was not explained properly. Users should know how a special workspace works thats why I gave an example so that people can understand it better.
* Work around GNU vs. BSD sed -i incompatibility
sed: 1: "src/modules/wlr/workspa ...": bad flag in substitute command: 'k'

* waybar-hyprland also exists on FreeBSD, so drop -git suffix
The path to execute the kde polkit agent has changed as of version 5.27.3, and now resides in /usr/lib64/libexec/polkit-kde-authentication-agent-1 instead. Because of this, the "must-have" page should have its instructions changed to reflect the update.
