Fix FirebaseServerApp Typescript exactOptionalPropertyTypes error (#8341)

This change fixes a TypeScript compilation error. 

The `FirebaseServerAppSettings.name` field inherited from `FirebaseAppSettings` but the type was redefined from `string` to `undefined`. This redefinition would cause a TypeScript compliation error if `exactOptionalPropertyTypes` was set `true` in `packages/app/tsconfig.json`.

This change now uses `omit< , >` to strip the `name` field from the `FirebaseServerAppSettings` declaration, where `FirebaseAppSettings` is extended.

Fixes #8336

+The `FirebaseServerAppSettings.name` field inherited from `FirebaseAppSettings` is now omitted
+instead of overloading the value as `undefined`. This fixes a TypeScript compilation error. For more
