Solution: install missing coreutils through Homebrew brew install coreutils

Stumbled on this on a new machine so I took a deeper look at the issue.

Adding coreutils isn't optimal because they're pretty heavy and install a lot of other not-necessarily-necessary things.

Some notes from a quick research:

• realpath is apparently back in macOS Ventura
• the issue was also dicsussed in places like this one: realpath doesn't exist on OSX whatwg/html-build#90 (although their needs are slightly different and the fix they implemented isn't a great solution for brut)
• This small shell function seems like a good solution to replace realpath. It can be added on top of brut's entry.sh script
