fix(gen2-migration): add awsRegion to userPoolConfig in additional auth providers (#14710)

* fix(cli-internal): add awsRegion to userPoolConfig in additional auth providers

The DataGenerator's contributeAdditionalAuthProviders method was
generating userPoolConfig with only userPoolId for
AMAZON_COGNITO_USER_POOLS auth providers. This adds the missing
awsRegion property (backend.auth.stack.region) so the generated
backend.ts matches the expected output.

Verified with existing data.generator.test.ts — all 14 tests pass.
---
Prompt: I've added this line in the mood-board snapshot. This
needs to be added whenever there is a userPool additional auth
provider - awsRegion: backend.auth.stack.region,

* chore: update snapshot manually

* chore: update snapshots
