STRATCONN-6671 - [LinkedIn Audiences] - membership update

[joe-ayoub-segment]

Updates the LinkedIn Audiences updateAudience action to support Segment's audienceMembership signal for determining whether a user should be added to or removed from an audience.

Previously, the action relied solely on the event name (Audience Entered / Audience Exited) to determine the ADD or REMOVE action sent to LinkedIn's DMP API.

This change adds a parallel path: when the actions-linkedin-audiences-audience-membership feature flag is enabled, the resolved audienceMembership boolean (derived from Engage or RETL event payloads) takes precedence over event name matching in AUTO mode.

Testing

New Unit tests added.
To be tested in Staging.
