add support for `vscode`

Hi, Although project name is 'terminal', I think it's better to add some editor like vscode.

Isn't there a file which saves the correct vscode-config which opens vscode when clicked in the folder?

problems i see:

• It is not the same goal of the plugin. (We could argue that the vscode contains an terminal emulator, but to be honest not really)
• In theory we also have to add every editor/program that exists. Where do we stop? I mean even lots of programs take a directory as input. Nextup someone could argue we could add kondo for cleaning up some files...

But somehow I see your point, that the program could be more generalized. We could extend everything such, that the config contains a command. In result we execute the command with the given directory. Not really sure what to do here.

Previously I only searched in AUR, but did not continue my search on the web. According to https://github.com/microsoft/vscode/issues/103412, seems Nautilus-OpenInVSCode solve this problem.

About the custom command issue, I thought simpler. The custom string consists of a comma expression, which represents the program, and two sets of parameters. They are parsed at program startup.

thanks for giving me the idea to generalize it. this kind of code would introduce multiple bugs, therefore i will close the issue. Additionally the value should not be only read when starting, but evaluate over and over again.
