chore(h): fix JSX runtime clean path

[nickshiro]

Summary

Fix the @solidjs/h clean script so it removes the package-local JSX runtime output. The previous /jsx-runtime/dist argument was an absolute path. As a result, rimraf looked for the directory at the filesystem root instead of cleaning packages/h/jsx-runtime/dist/. This could allow stale JSX runtime bundles, such as old CommonJS artifacts, to survive subsequent builds.

How did you test this change?

• Added a temporary stale artifact to packages/h/jsx-runtime/dist/.
• Ran pnpm --filter @solidjs/h run build.
• Verified that the stale artifact and old jsx.cjs output were removed.
• Verified that the current jsx.js bundle was regenerated.
