fix: bound langchain-anthropic<1.7.0 on uipath-langchain-client extras

langchain-anthropic 1.7.0 changed the private _create/_acreate contract
to raw responses, breaking every UiPathChatAnthropic operation. Bound
<1.7.0 on the anthropic extra and explicitly on the bedrock extra
(previously unbounded there via langchain-aws[anthropic]). Interim pin
until the overrides adopt the new contract.
