!!! BUGFIX: Browser arguments are the request parsed body

[albe]

Since 6.0 the Browser $arguments were accidentially moved to the request query parameters, while they should reflect the post body arguments.

The docblock even states that:
@param array $arguments Arguments to send in the request body

Note: this slightly changes behaviour if you adapted your usage of Browser since 6.0.0. If you want to send query parameters, you should instead provide an Uri instance with the parameters, as was already the case prior to 6.0. (This is the reason for marking this bugfix as breaking.)

Note to self: I should probably add a test for this.

Looks good to me now. Test confirms the expected behaviour. Maybe we should mark this BUGFIX as "breaking" to make aware of the changed (=fixed) behaviour?

Awesome, thank you for taking care!

Damn, I think I was a bit too quick with that one..
Is 6.0 the right target branch and should this be marked "breaking"?

If we want to revert this one => #2071

Well, it was breaking when upgrading from 5.x -> 6.x until now - but unintentionally at that. That's why I think it should land in 6.0+ - but maybe it should be marked as breaking and be clearly mentioned, so that an upgrade from older 6.x is not so unexpectedly changing things again (if you never came from 5.x for example).

I'd say we keep it like this now. I adjusted the description slightly and marked it as breaking.
