Additional keywords in .desktop file

[Surasia]

Currently, I don't have a keybinding for ghostty so I usually end up searching for it inside GNOME shell. I noticed that the keywords in the .desktop file only include these:

ghostty/dist/linux/app.desktop

Line 8 in 603639a

Keywords=terminal;tty;pty;

I feel like also including console, cmd and TerminalEmulator would make it easier to search. I did think of just making this into a PR but I think its worth a discussion.

I think "console" makes sense, I'm not sure how often Linux folks use the others?

Adding "console" and "cmd" makes sense to me, but I don't think that it makes sense to add "TerminalEmulator" when we already have "terminal" since one is a substring of the other.

@jcollie good point, was looking at other terminals for ideas and it was used for kitty.

Also for cmd, it's a bit of a habit from dual booting windows/linux and I know that it isn't proper terminology, but I'd still say it's a good search term and as short as something like "tty".

"commandline" maybe?
