Thank you for your contribution. Before submitting this PR, please include:

Id of the task, bug, story or other reference.

Description

Adding a performance improvement for post-chat loading: the postChatContext API in omnichannel-chat-sdk internally invokes getConversationDetails. Therefore, we can optimize by skipping the getConversationDetails call in endChat and directly using the postChatContext API instead.

Which will save 3 api calls from making to get the postchatContext
