Upgrade SWC and use React preset (#266)

Upgrading SWC deps because we need swc-project/swc#5499 for #252

This also switches from using the JSX preset to the full React preset.

@sokra noticed a drop in performance in #252 and one possible reason is the difference in processing between the SWC versions, or between the presets, so this PR acts as a way to isolate that particular change for benchmarks.
