fix(path): re-export normalizeHastElement from index

The initial commit added normalizeHastElement to src/path.ts but
forgot to include it in src/index.ts's top-level re-export list,
so importers doing `import { normalizeHastElement } from '@quartz-community/utils'`
would see 'has no exported member'. Imports via the /path subpath
worked, but the top-level entrypoint is the conventional import
surface for most consumers.
