fix(mcp): run the time preset with uvx mcp-server-time (#7863)

The time preset ran npx -y @modelcontextprotocol/server-time, but that
package does not exist on npm (404), so the server exited on start and
clients reported the connection as closed. The official time server is
published to PyPI as mcp-server-time; run it with uvx like the fetch
preset, and update the preset name, the name placeholder and the user
manual tables.
