v0.303.0

New Features:

• Adds a new stylex_shorthand_prop flowconfig option that enables syntactic sugar for StyleX on lowercase (intrinsic) JSX elements. When set to a prop name (e.g. stylex_shorthand_prop=sx), <div sx={[styles.foo, styles.bar]} /> desugars to <div {...stylex.props(styles.foo, styles.bar)} />.
