update sentry client in airbyte-ci/connectors/pipelines

## Problem

We have this warning show up in build logs whenever we build airbyte-ci/pipelines for testing:

```
/airbyte/airbyte-ci/connectors/pipelines/pipelines/helpers/sentry_utils.py:41: DeprecationWarning: sentry_sdk.configure_scope is deprecated and will be removed in the next major version. Please consult our migration guide to learn how to migrate to the new API: https://docs.sentry.io/platforms/python/migration/1.x-to-2.x#scope-configuring
with sentry_sdk.configure_scope() as scope:
```

To reproduce this, you can fetch the repo and then:

```bash
cd airbyte-ci/connectors/pipelines
poetry install
poetry run pytest .
```

## Solution

Upgrade poetry client to the recent version and clean up the code that sets sentry up. This should be a good first issue.
