Show applied migrations in CLI image (like hasura-cli does)

### Is your proposal related to a problem?

with debug log level, hasura-cli shows which migrations are applied. but the docker-cli image doesn't.

Here's `hasura-cli migrate apply --skip-update-check --project hasura --log-level DEBUG`


And here's the only information provided by `hasura/graphql-engine:v2.9.0.cli-migrations-v2` image with `HASURA_GRAPHQL_LOG_LEVEL: debug`

`{"timestamp":"2022-08-05T12:31:23.000+0000","level":"info","type":"startup","detail":{"kind":"migrations-apply","info":"applying migrations from /hasura/migrations"}}`

### Describe the solution you'd like

I would like the same debug lines to be present, one for each migration applied.

### Describe alternatives you've considered

There are none.

### If the feature is approved, would you be willing to submit a PR?

doubtful

Start with the `hasura/graphql-engine:v2.9.0.cli-migrations-v2` startup path and compare its `HASURA_GRAPHQL_LOG_LEVEL=debug` output with `hasura-cli migrate apply --skip-update-check --project hasura --log-level DEBUG`. Done means the Docker CLI image emits one debug line for each applied migration.
