document-loader: Documentation implies HTTP transfer support

[danielmarquard]

Describe the issue

The documentation for the document loader MCP implies that HTTP transport is supported when running with Docker, but the Dockerfile exposes no ports and the container confirms stdio transport at launch. I could really use these tools, but stdio won't cut it for running these tools at scale.

Edit: I modified the project to support streamable HTTP. Works great. But it'd be better if HTTP transport was officially supported.
