Fix tsc error for legacy module resolution.

[taeold]

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.

Summary of Changes

Hello @taeold, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request reintroduces the 'typesVersions' field in the 'package.json' file. This change is essential for maintaining compatibility with TypeScript projects that use the 'moduleResolution: node' setting. By explicitly mapping type definitions for various subpaths, it resolves compilation errors that occur when the 'exports' field is ignored by this legacy resolution mode. This ensures that users who have not yet upgraded to 'node16' or 'nodenext' module resolution can continue to compile their projects without issues.

Highlights

• TypeScript Compatibility: Restores the 'typesVersions' field in 'package.json' to resolve TypeScript compilation errors for projects configured with 'moduleResolution: node'.
• Legacy Module Resolution Support: Ensures continued compatibility for users who have not yet migrated their TypeScript projects to 'node16' or 'nodenext' module resolution strategies.
• Subpath Import Resolution: Addresses issues where the 'exports' field was ignored by the 'node' module resolution, preventing compilation errors when importing subpaths like 'firebase-functions/https'.

Code Review

This pull request restores the typesVersions field in package.json to ensure compatibility with legacy TypeScript module resolution (node). The change correctly adds the necessary type mappings for various subpaths, which should resolve the compilation errors for users on older setups. My review includes a couple of suggestions to improve the consistency and maintainability of the newly added configuration block.
