install.ps1: UNSLOTH_INSTALL_REF also drives the WSL unsloth install

Browse source 
So a branch can be tested end-to-end pre-merge: when UNSLOTH_INSTALL_REF is set
(not main), pass install.sh `--package git+https://github.com/unslothai/unsloth@<ref>`
so the WSL studio venv carries THAT ref's studio/setup.sh + unsloth Python patches
(otherwise install.sh installs released PyPI unsloth and the branch's setup.sh --
e.g. the WSL CPU-build skip -- never runs). Default (ref = main) is byte-identical
to before. The git URL has no spaces, so it survives PowerShell -> wsl.exe -> bash -lc.
