Add Support for JETLS

[rakeshksr]

Add support for JETLS, a new and emerging language server for Julia that serves as an alternative to LanguageServer.jl. Integrating JETLS could provide improved performance, better diagnostics, and a more modern foundation for language tooling within the Julia ecosystem.

Hello! thank you for the suggestion, i think it will be a good idea to offer JETLS as an alternative to LanguageServer.jl, however ill have to test it and see how it preforms compared to LanguageServer.jl. thank you very much for the suggestion!

Thanks for quick lookup. It's nice have an option in UI to select desired language server.

i have tested JETLS, its quite good, although their readme says its still not stable so i have labeled it in the IDE as experimental with an option to switch between the 2 in the settings, thank you once again!

I’ve opened PR #14 to fix the Jetls path issue on Windows.
