ansible, m1, libssh

For some reason I haven't been able to track down, the way that uv and ansible try to build libssh doesn't work by default with Homebrew on a Mac M1.

❯ time uv run --python python3.11 ansible-playbook -v site.yaml --ask-vault-pass -l somehostname.somedomain.net

      hint: This error likely indicates that you need to install a library that provides "libssh/libssh.h" for `ansible-pylibssh@1.2.2`
  help: `ansible-pylibssh` (v1.2.2) was included because `myansible` (v0.0.1) depends on `ansible-pylibssh`

The workaround, which I forgot from last time, is:

export C_INCLUDE_PATH=/opt/homebrew/include:$C_INCLUDE_PATH
export LIBRARY_PATH=/opt/homebrew/lib:$LIBRARY_PATH
