Fixes #8467

The previous fix ignored any pyenv command found in $PATH while on
WSL, regardless of whether it was correctly set up or not.

This change only ignores the pyenv command if it's proved to come
from pyenv-win by looking at its full path.

This change fixes the setting of $PATH for pyenv and its shims, while warning
the user about non-interactive shells.

Add --no-rehash to the pyenv init command, which was removed in [#4492].

The rehash was likely disabled because it can affect shell startup times.
It should only be necessary when installing or removing Python versions.

See [pyenv/pyenv#784] and [sorin-ionescu/prezto#1603] for more detail.

[#4492]: https://github.com/ohmyzsh/ohmyzsh/pull/4492
[pyenv/pyenv#784]: https://github.com/pyenv/pyenv/issues/784
[sorin-ionescu/prezto#1603]: https://github.com/sorin-ionescu/prezto/pull/1603

This solves the problem where the used pyenv is actually the one in a
Windows folder, instead of in WSL.

Fixes #9034

This is needed if in between the update of `$PATH` the `$commands` parameter hasn't
been updated, i.e. if there was no `rehash` or `hash -rf` or automatic rehash.

* Refactor pyenv plugin to use PATH
