add Zig module icons
Nerd fonts as of now does not support an icon for Zig. I think it would be better to first make a pull request on their side and add such an icon prior to adding it to this project.
Unicode 21af is not a part of Nerd Fonts. According to a collaborator, this project likely does not use icons that do not come from Nerd Fonts..
On top of that, your commit seems to add the icon for a .zig hidden file instead of adding the icon to a file with the extension .zig.
Hello, it would appear as if Nerd Fonts has added support for zig. Specifically, gliph \ue6a9. Note that this appears to be different from the one that this PR is trying to merge.
Is there any other blockers to this, besides the gliph code being wrong?
