Issue when installing on macos-14

[petitlapin]

Hi, thanks for the action!

It was working fine with macos-13, but a few days ago github switched macos-latest to macos-14 and it causes some issues with the action:

Run turtlebrowser/get-conan@main
Run pip3 install wheel setuptools
error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try brew install
    xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a Python library that isn't in Homebrew,
    use a virtual environment:
    
    python3 -m venv path/to/venv
    source path/to/venv/bin/activate
    python3 -m pip install xyz
    
    If you wish to install a Python application that isn't in Homebrew,
    it may be easiest to use 'pipx install xyz', which will manage a
    virtual environment for you. You can install pipx with
    
    brew install pipx
    
    You may restore the old behavior of pip by passing
    the '--break-system-packages' flag to pip, or by adding
    'break-system-packages = true' to your pip.conf file. The latter
    will permanently disable this error.
    
    If you disable this error, we STRONGLY recommend that you additionally
    pass the '--user' flag to pip, or set 'user = true' in your pip.conf
    file. Failure to do this can result in a broken Homebrew installation.
    
    Read more about this behavior here: <https://peps.python.org/pep-0668/>

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
Error: Process completed with exit code 1.

For now, instead of using macos-latest, I switched to macos-13, so not a blocking issue.
Thanks again for the action!

Adding a setup-python to the workflow works: https://github.com/actions/setup-python

For example:

steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
    with:
      python-version: '3.10' 
- name: Get Conan
      uses: turtlebrowser/get-conan@main
