Removed the composer and php aliases and instead added a small script to call the correct php binary.
This script is placed in the macos bin folder and we add the folder to the PATH in the .zprofile within the install-mac.sh.
Adding it after brew registers its paths, allows our script to be priortized instead of the currently linked php binary.
Because the .zprofile file is used to setup environment variables and it being called for non-interactive sessions too, calls to php in JS scripts for example will now correctly use the isolated php version via valet.
Fixes annoying pecl update issues & swoole build failures by using the prebuilt tap.
This also properly manages updates & enables the extensions via files in conf.d instead. Very clean.
And it finally properly installs all extensions for all php versions, pecl has issues with properly installing for other php versions.
This is unused, since we are using lua plugins now and also does not work anymore, because Homebrew follows PEP668, which discourages installing packages without the package manager or outside of a venv.
