fix(es/transforms): Correct span for @jsxFrag as null literal

[nayeemrmn]

• Will fix .. Panic when running JSX file with both @jsxImportSource and @jsxFrag null pragmas denoland/deno#30216

The expression span for @jsxFrag null wasn't being adjusted. This was leading to a source map panic when trying to format the error for error: pragmaFrag cannot be set when runtime is automatic.

If it needs a test, please let me know how to add fixtures for expected parse failures.
