Macvim from Homebrew formula missing ruby@4.0

Steps to reproduce

Install macvim via homebrew via brew install macvim and then either launch the macvim via GUI or terminal. The error message I got is:

Vim and MacVim configuration where issue is reproducable

No response

How was MacVim launched?

• by launching MacVim.app in macOS (by using the Dock, Spotlight, or the open command)
• by running mvim/gvim in the terminal

Issue has been tested with clean configuration

• by running mvim --clean (or gvim, supplied by MacVim distribution). You can also use the File → "New Clean Window" menu item within MacVim.
• by running vim --clean (in terminal, supplied by MacVim distribution)
• by running vim --clean (in terminal, other suppliers, e.g. /usr/bin/vim)

Inizia riproducendo il malfunzionamento con brew install macvim, quindi esamina la formula Homebrew e i relativi punti di ingresso delle dipendenze o della compilazione per individuare la libreria ruby@4.0 mancante. Il lavoro è completo quando un avvio pulito di MacVim funziona sia tramite MacVim.app sia tramite mvim/gvim, anche con --clean.
