[FR]: 'include_npx' for js_binary

[gregjacobs]

What is the current behavior?

There's currently an include_npm attribute for js_binary (https://github.com/aspect-build/rules_js/blob/main/docs/js_binary.md#js_binary-include_npm) to include the npm executable, which is great.

However, I'm using a package called icon-font-buildr which actually spawns npx at runtime. Currently I'm getting away with this because our CI machine has Node/npm/npx installed so I'm using the system path for it, but would ideally like to get this to work with RBE and systems that don't have Node already.

Describe the feature

Wondering if it would be possible to add an include_npx attribute for js_binary?

Or perhaps it would be better to just add a symlink for npx when include_npm is true? Thoughts?
