icon request: zsh

[guppy0130]

Is your icon request related to a problem? Please describe.
No particular problem, just thought it would be neat to see the zsh logo when opening a zsh shell in vscode :)

Describe the solution you'd like
Adding the zsh icons from their (official?) repo

Noticed that in #68 it was requested to have the svg, so I think https://github.com/Zsh-art/logo/blob/main/svg/white_vertical_icon.svg?short_path=c7a2046 would be sufficient? The only potential issue I see with this is that I see your other icons use fill="currentColor" (assuming for coloring in different usage scenarios?) while they have hardcoded stroke colors.

Describe alternatives you've considered

• Using the default terminal icon (current behavior), which is fine, but the zsh icon would be more specific
• terminal-linux is also ok, but again, could be more specific
• terminal-{bash,ubuntu,debian,tmux} aren't correct

Additional context

Since zsh is the default shell on macOS, I don't think we should do this (at least on that platform). Right now we use the default terminal icon for that:

Using the %_ could be confusing for new users.
