### 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)

Start with data/resource.ts and the amplify.yml pipeline command, then reproduce the deployment with the added Todo model. Compare the successful deployment's amplify_outputs.json with the generated schema and configuration; done means the new model's types and configuration are present immediately after deployment rather than appearing later.
