Nylas::CalendarCollection.availability returns Nylas::InvalidRequest when :round_robin parameter is nil

[kwayebopp]

Describe the bug
Using nil as the value for the :round_robin parameter returns a Nylas::InvalidRequest error.

To Reproduce
Simply try calling the availability function on a Nylas::CalendarCollection. After looking through the codebase, :round_robin appears to be nil by default, so I think the bug should surface with whatever parameters you use.

nylas =  Nylas::API.new(...)
nylas.calendars.availability(
  #params go here
)

Expected behavior
As per the developer docs, I expected that using round_robin: nil would return collective availability.

SDK Version:
5.11.0

Thanks for your patience @kwayebopp. After talking to the availability team, it seems the documentation is off. round_robin is optional, but null is not a valid value. Omitting the round_robin field will yield a successful result with collective availability. Sending null will return an error.

I opened a PR to address this, now we just omit the field if it's left to nil. We also opened an internal ticket to fix the docs to reflect this. Thanks again for spotting and reporting this issue!
