docs: update wsl installation procedure (#9968)

This is a 🔦 documentation change.

## Summary

The install documentation for WSL offers to install Ruby through
BrightBox. However, BrightBox does not support Ubuntu Jammy (which is
the default for latest WSL builds). Instead, this commit just redirects
the WSL user to the Ubuntu installation procedure to avoid duplicate
documentation.
