Describe the bug

When using Amplify Gen 2 , and making some updates in data/resource.ts (AppSync schema), the updates on models, configurations are not reflected in amplify_output.json after the deployment succeeded. Even though the logs (deployment logs) shows [INFO]: File written: amplify_outputs.json in fact latest changes are not written there.

Funny fact, if you download the amplify_output.json the next day, changes are reflected ))) The most hilarious bug ever seen I guess (some async things going on)

Here is the backend build in amplify.yml

backend:
  phases:
    build:
      commands:
        - npm ci --cache .npm --prefer-offline
        - npx ampx pipeline-deploy --branch $AWS_BRANCH --app-id $AWS_APP_ID

Reproduction steps

Given the following schema

const schema = a.schema({
  Account: a.model({
    identity: a.id().required(),
    email: a.email()
  }).identifier(['identity']).authorization(allow => [allow.owner()])
})

Add a new model for example :

const schema = a.schema({
  Todo: a
      .model({
        content: a.string(),
      }).authorization(allow => [allow.owner()]),
  Account: a.model({
    identity: a.id().required(),
    email: a.email()
  }).identifier(['identity']).authorization(allow => [allow.owner()])
})

Expected is that after deployment using CI/CD Gen 2, the types and everything regarding new model should be defined and written in the amplify_outputs.json, while this is not happening (the file get's updated only after a day)
