jsonc (and yaml/toml) configuration file support

[csjewell]

Clear and concise description of the problem

I like being able to put comments in my json files. I understand that (updated versions of) c12 support those file formats, so it SHOULD be as easy as changing the line I linked in the "Suggested solution" area. If I get time soon, and you'd like, I'll create a PR (cannot do it until Saturday at least, sorry!)

Suggested solution

This should be the line to change, if I'm understanding your code correctly:

bumpp/src/config.ts

Line 42 in 6887d41

const candidates = ['js', 'mjs', 'ts', 'mts', 'json'].map(ext => `${name}.config.${ext}`)
