Pull request overview

Fixes invalid JS generation in the React Native Babel plugin’s getContent output by ensuring JSX attributes with non-identifier names (notably hyphenated ones like aria-hidden, data-testid) are emitted as quoted string keys, avoiding Hermes parse errors.

Changes:

• Update jsxChildToRuntimeCall to emit object property keys as identifiers only when the JSX attribute name is a valid JS identifier; otherwise emit a string literal key.
• Add test coverage ensuring hyphenated attribute names are quoted in getContent, while valid identifier attribute names remain unquoted.
