community[minor]: add allow_dangerous_requests for OpenAPI toolkits (#19493)

**OpenAPI allow_dangerous_requests**: community: add
allow_dangerous_requests for OpenAPI toolkits

**Description:** a description of the change

Due to BaseRequestsTool changes, we need to pass
allow_dangerous_requests manually.


b617085af0/libs/community/langchain_community/tools/requests/tool.py (L26-L46)

While OpenAPI toolkits didn't pass it in the arguments.


b617085af0/libs/community/langchain_community/agent_toolkits/openapi/planner.py (L262-L269)


**Issue:** the issue # it fixes, if applicable

https://github.com/langchain-ai/langchain/issues/19440

If not passing allow_dangerous_requests, it won't be able to do
requests.

**Dependencies:** any dependencies required for this change
