New glyphs: GlimmerJS and GlimmerTS
Hello, I'd like to request that we add glyphs for the gjs and gts file extensions.
I'm willing to do the work, but wanted to open an issue, as recommended here: https://github.com/ryanoasis/nerd-fonts/discussions/1095



**Requirements**

- [x] I have searched the [issues](https://github.com/ryanoasis/nerd-fonts/issues) for my request and found nothing related and/or helpful
- [x] I have searched the [FAQ](https://github.com/ryanoasis/nerd-fonts/wiki/FAQ-and-Troubleshooting) for help
- [x] I have searched the [Wiki](https://github.com/ryanoasis/nerd-fonts/wiki) for help

**Is your feature request related to a problem? Please describe.**

I know that nerd-fonts aggregates from a few glyph sets: https://github.com/ryanoasis/nerd-fonts/wiki/Glyph-Sets-and-Code-Points
so I don't know that it's exactly nerd-fonts' responsibility to add new glyphs -- but I'd like to know where to get started -- should I ask Devicons to add the new glyphs for the single-page-app framework file extensions?

**Additional context**
