### Describe the problem that is addressed by this PR
Customer escalated the issue:
The issue was introduced from the @azure/communication-chat@1.4.0. Chat
client updated the internal API client by generating the new service
client version with the `endpoint` param to replace the `baseUri` and
kept the dependency version @azure/core-client@1.3.0 and higher. While
the `endpoint` is introduced only in @azure/core-client@1.6.0.
Customer see error "baseUrl is not specified" if the dependency version
not updated.
