[FEATURE] Filter for labels in Gmail trigger

[andrewjschuang]

Is your feature request related to a problem? Please describe.
I want to choose label filters (e.g. only from INBOX) in the Gmail - New Email Received trigger.

Additional context
Requested by a user.

Hi @andrewjschuang. Can you provide any additional information about this request? The Gmail triggers new-email-received, new-email-matching-search, new-attachment-received, and new-labeled-email all support filtering by label.

The user wants to avoid specific labels like promotions, so maybe the solution is to add an optional prop to ignore selected labels.

Also the label prop is a string type, it makes more to change it to string[].
