Remove policies-updater ECS task (#1046)

### Feature or Bugfix
- Bugfix

### Detail
In data.all there are 7 ECS Tasks:
Tasks currently being used:
- cdkproxy -- on demand - it deploys CDK stacks in Environment accounts
- share-manager -- on demand - it executes sharing actions
- stacks-updater -- on schedule every 1day - Every day environment and
dataset stacks are updated

Tasks that need to be reviewed:
- subscriptions -- on schedule every 15mins - it tries to poll message
from subscriptions queue. The queue is empty and we are not posting any
messages. We could consider subscriptions to be legacy at the moment.
- catalog-indexer -- on schedule every 6hours - it reads all active
items from RDS and indexes them in the Catalog. It does not look for
deleted items.
- tables-syncer -- on schedule every 15mins - it reads all active
datasets. With boto3 it reads the Glue tables in that database and syncs
the Glue tables with the registered tables in data.all. It upserts in
OpenSearch and grant LF permissions.

Tasks that currently are not used and need to be removed:
- policies-updater -- on schedule every 15mins - it reapplies shares on
imported buckets. It is legacy from folder sharing based on bucket
policies. It uses the generic ecs-tasks-role

In this PR the task policies-updater is removed

Tested in AWS
- [X] CICD pipeline succeeds
- [X] ECS CFN stack is updated and deleted policies-updater task. It
also deletes log-group. All other tasks remain untouched
