 Exclude content-type header from get_http_headers() to prevent HTTP 415 errors (#3104) 
Fixes #3097

When using FastMCP.from_openapi() with APIs that require specific
Content-Type headers (e.g., application/vnd.api+json), the transport
connection's content-type: application/json was being injected into
downstream API requests, causing HTTP 415 (Unsupported Media Type) errors.

This change adds content-type to the exclude_headers set in get_http_headers(),
similar to how accept is already excluded. The MCP transport's content type
has no relevance to downstream API calls and should not be forwarded.
