Cygwin isn't the only edge-case for a differing bin/ path. In addition there
also is MSYS2, which behaves differently than Cygwin. CPython compiled against
Microsoft Visual C++ Runtime (MSVCRT) through MinGW, will correctly identify as
an 'nt' platform, yet will prefer a POSIX path scheme.
In order to avoid having to patch every edge-case, we can spy on the system
configurations install paths through the `sysconfig` module and get the basename
of the global scripts path, which will be returned in accordance with the
preferred install path scheme of the system/platform.

otherwise, installing the hooks when RENV_USER env variable is set (e.g. in RStudio with renv project) will result in executing the installation script in the wrong renv
This patch adds 2nd class support for hooks using julia as the language.
pre-commit will install any dependencies defined in the hooks repo
`Project.toml` file, with support for `additional_dependencies` as well.
Julia doesn't (yet) have a way to install binaries/scripts so for julia
hooks the `entry` value is a (relative) path to a julia script within
the hooks repository. When executing a julia hook the (globally
installed) julia interpreter is prepended to the entry.
Example `.pre-commit-hooks.yaml`:
```yaml
- id: foo
name: ...
language: julia
entry: bin/foo.jl --arg1
```

RubyGems allows OS packagers to specify defaults for `--install-dir`
and `--bindir` and these take precedence over `GEM_HOME`. The only way
to override the defaults is to explicitly specify the options ourselves
when running `gem install`.
Examples of OSes where this is the case are RedHat 9.2 and Gentoo.
Fixes#2799.
