Upgrade setuptools and wheel in the auto-install command (#6282)

Browse source 
The generated install command builds unsloth from git with
--no-build-isolation, so pip uses the environment's existing setuptools
rather than the pinned build-system requirement. On setuptools < 77 the
PEP 639 license string in pyproject.toml fails to validate and the
install aborts. Upgrade setuptools and wheel up front so the source
build always has PEP 639 support.
