Special case error message when wheel is missing with no build isolation

[konstin]

          I have problems with [`xformers` by Meta](https://github.com/facebookresearch/xformers) (see [issue](https://github.com/facebookresearch/xformers/issues/940)). I even tried with latest `uv` _without build isolation_:

❯ uv pip install setuptools torch numpy
Resolved 11 packages in 2ms
Installed 1 package in 23ms
 + numpy==1.26.4

❯ uv pip install xformers --no-build-isolation
Resolved 11 packages in 2ms
error: Failed to download distributions

Also posting the solution provided by @charliermarsh : you just have to install wheel.

(Also: will you eventually re-implement wheel so that uv can handle these cases?)
