Fix tsc error for legacy module resolution. (#1763)

We restore 'typesVersions' in package.json to support TypeScript projects using 'moduleResolution: node'.

This legacy resolution mode ignores the 'exports' field, causing compilation errors when importing subpaths like 'firebase-functions/https'. Restoring 'typesVersions' ensures compatibility for users who haven't migrated to 'node16' or 'nodenext' resolution.

Unblocks firebase/functions-samples#1227.
