Using hyprctl: clarify usage of `hyprctl setprop` and `exec` dispatcher with dynamic rules (#696)

 The `exec` dispatcher supports adding rules. Please note some windows might work
 better, some worse. It records the PID of the spawned process and uses that. For example, if
 your process forks and then the fork opens a window, this will not work.
+Rules will only be applied once. This means dynamic rules will be overridden as soon as a 
+property of the window changes (e.g. switching focus). To make dynamic rules stick around
+use `hyprctl setprop` (see [Using hyprctl](./Using-hyprctl)).

+Usage:

+Regex supports different modes. The supported modes are:

+class - class
+title - title
+initialclass - initialClass
+initialtitle - initialTitle
+active - active window
+address - address prefixed with 0x
+pid - process ID
+floating - first floating window on the current workspace
+tiled - first tiled window on the current workspace

+To get more information about a window, you can use `hyprctl clients`.

+Please beware that `hyprctl clients` will display the fields as **initialClass** and **initialTitle** while the regex mode uses `initialclass` and `initialtitle`.
