Fixes#11246
## Summary
This change adds an intermediate additional search path for
`find_ruff_bin`.
I would have added this path as the last one, except that the last one
is the one reported to the user, so I made this one second to last.
## Test Plan
It's shown to work with this command:
```
~ @ pip-run git+https://github.com/jaraco/ruff@feature/honor-install-target-bin -- -m ruff --version
ruff 0.4.4
```
I tried running the same command on Windows, which should work in
theory, but building ruff from source on Windows is complicated. Even
after installing Rust, ruff fails to build when `libmimalloc-sys` fails
to build because `gcc` isn't installed (and the error message points to
a [broken
anchor](https://github.com/rust-lang/cc-rs#compile-time-requirements)).
I was really hoping Rust would get us away from the Windows as
second-class-citizen model :(.
This saves a handful of milliseconds on Windows and even more on other
platforms when running `python -m ruff`. On non-Windows systems the
process is replaced directly (impossible on Windows unfortunately).

## Summary
From the [subprocess
docs](https://docs.python.org/3/library/subprocess.html#subprocess.Popen):
> Changed in version 3.6: args parameter accepts a path-like object if
shell is False and a sequence containing path-like objects on POSIX.
>
> Changed in version 3.8: args parameter accepts a path-like object if
shell is False and a sequence containing bytes and path-like objects on
Windows.
We want to support python 3.7 on windows, so we need to convert the
`Path` into a `str`
Fixes#5077
## Summary
Previously, in a powershell on windows when using `python -m ruff`
instead of `ruff` a call such as `python -m ruff "a b.py"` would fail
because the space would be split into two arguments.
The python docs
[recommend](https://docs.python.org/3/library/os.html#os.spawnv) using
subprocess instead of os.spawn variants, which does fix the problem.
## Test Plan
I manually confirmed that the problem previously occurred and now
doesn't anymore. This only happens in a very specific environment
(maturin build, windows, powershell), so i could try adding a step on CI
for it but i don't think it's worth it.

Prefer the version from a currently active virtualenv over a version
from `pip install --user`. Add the .exe extension on Windows, and
find the path for `pip install --user` correctly on Windows.
