Add the possibility to enter the StartupWMClass

[Soljanka]

OS: elementary OS 6.1 Jólnir x86_64
Pin It!: com.github.ryonakano.pinit 1.4.1

I really prefer using Pin It! over other applications like menulibre since it fits the minimalistic design of elementary OS. Yet there is one feature that I do miss: a way to add the StartupWMClass to the .deskop file.

Without the StartupWMClass applications will usually run in another instance and not use the entry I pinned to plank:

(Papers, Please does not use the entry I pinned to the dock but another instance without an icon)

This means I usually have to open the .desktop file with a text editor anyway.

(after addin the StartupWMClass; Papers, Please is not shown as running in another instance)

Proposal: another line in the "Edit Menu" for the Startup WM Class, much like in menulibre

bonus points for a picker, e.g. click on the magnifying glass and then on the application window to get the correct value
