Story (Required)

The segment analytics provider doesn't use standard .fromConfig signature that backstage docs recommends - https://backstage.io/docs/plugins/analytics/

 
SegmentAnalytics.fromConfig(configApi, identityApi)

Background (Required)

https://issues.redhat.com/browse/RHDHPAI-752 required us to create a new extension for Analytics APIs. For that we need all the analytics API using this extension to have a standard API signature where the class can be instantiated using .fromConfig static method. This static method needs to follow a signature like this - 
SegmentAnalytics.fromConfig(configApi,

)
**

Acceptance Criteria (Required)

• Should update the Segment analytics plugin to use recommended API signature.
