Similar to `rbenv-sync` and `nodenv-sync`, but for use with `pyenv`. Python has separate formulae for minor Python versions, as such this will symlink all patch versions to the latest minor version.

|
Create symlinks for Homebrew's installed Python versions in ~/.pyenv/versions.
|
|
|
|
Note that older patch version symlinks will be created and linked to the minor
|
|
version so e.g. Python 3.11.0 will also be symlinked to 3.11.3.
