Getting musl binaries version of an extension on glibc platform

[hsnoil]

Bug Description:

I loaded up the rust-analyzer plugin and found that it wasn't working on the appimage. I tried to run the binary it shows manually and it said "file or directory not found", doing a file rust-analyzer it reported that the interpreter was ld-musl. I checked with my vscodium version and it is ld-linux. Copying the binary from vscodium and it worked

Steps to Reproduce:

1. Get the Theia appimage from eclipse website and run it
2. Install rust-analyzer plugin
3. It will not work, the output tab will display an error

Additional Information

By getting the file inside the outputs tab it points to rust-analyzer --version. Using file to check it points to musl interpreter. Swapping it manually with the one from vscodium binary makes it work

• Operating System: Linux
• Theia Version: 1.50.1

Hey @hsnoil,

this is a duplicate of #13558, Theia currently does not respect the platform version property when downloading an extension.
