Update to latest schema version 2025-10-17

[joelverhagen]

What does this PR do?

The MCP Registry has iterated the schema version two more times, and has now locked it as a "v0.1". Fortunately this new schema version does not actually impact us but the MCP Registry does assert the new schema URL.

See https://github.com/modelcontextprotocol/registry/blob/main/docs/reference/server-json/CHANGELOG.md

@chidozieononiwu PTAL

[anuchandy]

Looks like server.json is removed as part of this PR -https://github.com/microsoft/mcp/pull/1375/changes - and it doesn't seem we have a dependency on the schema version anymore. Hi Dozie @chidozieononiwu , could you double-check? If the changes are outdated or no longer relevant, please help close it.
