feat(disjunctiveFacetParams): reduce payload size

[Jerska]

This PR reduces the amount of params sent for each disjunctive facet request. It also reduces hitsPerPage from 1 to 0, allowing us to remove the attributes* parameters at the same time.

This reduces:

• the payload sent by a few bytes
• and the response size by a few extra bytes as the previous implem sent back one objectID per additional request

this looks great! I've tried it out in a sandbox here and everything works as expected https://codesandbox.io/s/javascript-helper-app-forked-jyn60w?file=/src/app.js

Could you update the tests too?

[Jerska]

Yes I'm on it, but I'm currently struggling with the node-sass version not being compatible with node 16 ^^" Thanks for trying on a sandbox !

We can replace node-sass with dart-sass in another PR since the former is deprecated.
