Python: Fix MCPStreamableHTTPTool to use new streamable_http_client API (#3088)

Browse Source 
* Fix MCPStreamableHTTPTool to use new streamable_http_client API with proper httpx client cleanup

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Update docstring to reflect new streamable_http_client API usage

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Refactor MCPStreamableHTTPTool to accept optional http_client parameter and delegate client creation to streamable_http_client

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Update mcp package minimum version to 1.24.0 for streamable_http_client API support

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Fix critical bugs: apply headers/timeout/sse_read_timeout when creating httpx client, add version constraint <2, and properly manage client lifecycle

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Simplify implementation: remove headers/timeout/sse_read_timeout params, remove kwargs, remove close() override per feedback

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Add back **kwargs parameter for backward compatibility (accepted but not used)

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* Remove unused httpx import from test file

Note: The uv.lock file needs to be updated with 'uv sync' to reflect the mcp version constraint change (>=1.24.0,<2)

Co-authored-by: eavanvalkenburg <13749212+eavanvalkenburg@users.noreply.github.com>

* cicd fixes

* udpated samples with headers examples
