Add which to dependencies for yarn berry

[jackw]

This PR adds which as a dependency of this project which should make yarn berry PnP projects happy.

When using this package in a yarn berry project, yarn berry complains about it trying to access which.

Error: @npmcli/run-script tried to access which, but it isn't declared in its dependencies; this makes the require call ambiguous and unsound.

Required package: which
Required by: @npmcli/run-script@npm:4.1.3 (via /Users/jackwestbrook/Projects/grafana/.yarn/cache/@npmcli-run-script-npm-4.1.3-e85355f10b-62fb1a0e12.zip/node_modules/@npmcli/run-script/lib/)

Require stack:
- /Users/jackwestbrook/Projects/grafana/.yarn/cache/@npmcli-run-script-npm-4.1.3-e85355f10b-62fb1a0e12.zip/node_modules/@npmcli/run-script/lib/make-spawn-args.js

This results in needing to add the following to .yarnrc.yml in a yarn berry project:

packageExtensions:
  "@npmcli/[email protected]":
    dependencies:
      which: ^2.0.2

Looking at the code it appears make-spawn-args.js does indeed pull in the nested which dependency.
