fix: fixed cohesion snippet loading

[ayesha-waris]

INF-1676

Description
In the Authn MFE, we need to send a Segment Identify call that includes the Cohesion anonymous_id as a trait so that Segment is able to map Cohesion’s server-side events with Segment’s client-side events on the same page.

In the integration doc, there is a snippet of code that needs to be added to the already-existing code in Authn MFE to send Identify calls to Cohesion.
