[REQUIRED] Describe your environment

• Operating System version: macOS 13.1
• Browser version: NA
• Firebase SDK version: 9.19.0
• Firebase Product: auth

[REQUIRED] Describe the problem

Steps to reproduce:

• Try to compile an Angular project using Firebase 9.19.0
• The compilation fails with the error

Error: node_modules/@firebase/auth/dist/auth-public.d.ts:3225:23 - error TS2304: Cannot find name 'FactorId_2'.

The auth-public.d.ts file does indeed seem to reference a FactorId_2 symbol that doesn't exist.

It's documented as excluded at line 1160 of the file:

/* Excluded from this release type: FactorId_2 */
