Support non-greedy in regex

[ModProg]

Is your feature request related to a problem?

When using builtins.match I'd like to be able to do non-greedy matches.

Proposed solution

Add support for ? in combination with e.g. * or +.

Alternative solutions

I could probably use {0,x} where I increase x slowly until I get a match therefor implementing this in nix instead of relying on a regex feature.

Example:

❯ nix repl
Nix 2.24.7
Type :? for help.
nix-repl> builtins.match "(.*?)[ab].*" "zab"
[ "za" ]

I would have expected z because .*? should be non greedy
