Removing mirror list from FW bundle response

[akshith-gunasheelan]

Description

This PR addresses an issue in the Terraform provider where firmware URIs referencing external repositories could not be read correctly. The problem stemmed from improper parsing of the mirrorList field, which caused all associated fields to be returned as null. As a result, even though the configuration structure was valid, the provider failed to reflect the actual state accurately.

Fix:
We are removing the use of the mirrorList attribute, as the required URIs are already accessible through another field. Since mirrorList is redundant in this context and causes issues with state reading, its removal simplifies the logic and ensures accurate state reflection in Terraform.
