Describe the bug
The change in 7.7.1 breaks event list calls for google calendar when sending an array of values for the eventType ListEventQueryParams

To Reproduce
For a google integration, call the following:

nylas.events.list({ eventType: ['default', 'outOfOffice', 'focusTime'] })

The response returns a 400:

{
  error_obj: {
    code: 400,
    message: "Invalid string value: 'default,outOfOffice,focusTime'.  Allowed values: [birthday, default, focusTime, fromGmail, outOfOffice, workingLocation]"
  }
}

Expected behavior
When sending an array of ListEventQueryParams to a google calendar integration, the request is formed in a legal way for the google api and no errors are returned.

SDK Version:
I believe this change was introduced in 7.7.1

Additional context
If I roll back to my previous version, it works properly (7.5.2). We experienced this when updating the sdk.
