paramsSerializerOptions: arrayFormat does not seems to work.

[omarkhatibco]

Hello,

I'm trying to use arrayFormat but it does not seems to work, as in the docs

paramsSerializerOptions: {
    qs: {
        arrayFormat: 'brackets',
    },
},

I'm not sure it's a bug since there is no qs library installed anyway. does this option only works if axios is used?

Update: I just tried to provide a custom params serializer function, it's not used in the generated code and all the code are using URLSearchParams

I think we need much better documentation: https://orval.dev/reference/configuration/output#paramsserializeroptions

I have no idea what qs means or what the options for arrayFormat are! Or even any explanaton on what paramsserializeroptions is used for or what problem it solves.
