* 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
* Added wikipedia links to regex topic.
So that people who don't know much about regex/programming in general can read the regex topic from wikipedia in details.
* Edited no_direct_scanout description
It is very important because many people are having graphical issues with their game and setting no_direct_scanout to true works. See this discord link (https://discord.com/channels/961691461554950145/961694014615208048/1091353694974517349) from the hyprland discord server. See this video - https://0x0.st/HHLn.mp4
* Added the regex cheatsheet link.
Added the regex cheatsheet link to the swallow_regex description box. Users should need to know what are the different types of regexes and how to use them so that they can swallow whatever window they want.
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.
