Free-busy for `emails` is not supported by the EAS provider

[anirban-tw]

Bug Description
I am using nylas gem version 5.13.0 to fetch free_busy slots, getting the error Free-busy for 'emails' is not supported by the EAS provider with a Microsoft outlook email id.

To Reproduce
The code snippet used is as follows:

nylas = Nylas::API.new(
    app_id: ...,
    app_secret: ...,
    access_token: ...
)
coll = client.free_busy(emails: ['[someid]@outlook.com'], start_time: 1668784065, end_time: 1673968065)
coll.each{ |item| puts item}

the code when executed throws the following exception:

../http_client.rb:227:in `handle_anticipated_failure_mode': Free-busy for `emails` is not supported by the EAS provider. (Nylas::InvalidRequest)

Expected behavior

Should return a list of free busy slots

SDK Version:
nylas gem version 5.13.0
