Add support for more script files

[what1s1ove]

Hey guys!

Before using your package, I used a Makefile as a file to store all my application scripts (not the scripts section in package.json). There are many reasons for this (comment support, variables, working with all platforms (Deno, Bun, etc.), and so on). I migrated the scripts to package.json along with your package since I have fairly small projects. However, as a future plan, you might want to consider expanding support for script files.

Knip has support for bash/script files, plugins like husky, lefthook and lint-staged use this.

Depending on the generic usefulness we could think of a new plugin? I have no idea if parsing a Makefile is feasible (for bash-parser)?

If you're interested, you can search for "bash parser" and "tree sitter" in this repo for some drama around the topic :)
