Update StrictReactDOMSelectProps.js

The \`disabled\` prop was missing from \`StrictReactDOMSelectProps\` while present on input, textarea, button, option, and optgroup. \`<select disabled>\` is valid HTML and already worked at runtime (it's in the prop allowlist and handled by the native renderer), so typed consumers hit a false type error. This adds the type declaration; the generated \`.d.ts\` now exposes it to TS consumers too.
