Changes code blocks for notification examples to use `typescript` fence
instead of `json`. This properly represents TypeScript types (like
Record<string, unknown>, CallToolResult, Partial<HostContext>) without
quotes, matching the format used elsewhere in the specification.
Affected notifications:
- ui/notifications/tool-input
- ui/notifications/tool-input-partial
- ui/notifications/tool-result
- ui/tool-cancelled
- ui/resource-teardown
- ui/size-change
- ui/host-context-change
- ui/notifications/sandbox-ready
- ui/notifications/sandbox-resource-ready
