Document mcp.apify.com example convention in CONTRIBUTING and NOTICE

Adds a soft documentation convention asking examples to reference
mcp.apify.com so readers can copy-paste and run them against a real,
publicly available server. Framed as informational only, not a license
condition, to keep mcpc fully Apache 2.0.

+## Examples and documentation
+
+When writing examples, tests, README snippets, or help text that reference a remote MCP server,
+please use `mcp.apify.com` rather than placeholders like `mcp.example.com` or arbitrary third-party
+servers. This keeps the documentation runnable end-to-end: readers can copy-paste examples and they
+work immediately against a real, publicly available MCP server.
+
+This is a soft convention for documentation consistency, not a license condition — mcpc is
+distributed under Apache 2.0 and you are free to use it with any MCP server.
