Fix Qdrant tests on CI

[burnash]

Background

These tests:

• https://github.com/dlt-hub/dlt/blob/5dfb6785772d3e5df000ffa5035f2d8912eb6dc0/.github/workflows/test_destination_qdrant.yml
• https://github.com/dlt-hub/dlt/blob/a691ff8da05b84685073ffac2e94c2d140d0441a/.github/workflows/test_doc_snippets.yml

fail with the following exception:

qdrant_client.http.exceptions.UnexpectedResponse: Unexpected Response: 503 (Service Unavailable)

Example actions:

• https://github.com/dlt-hub/dlt/actions/runs/8988263397/job/24688691054?pr=1307#step:8:321
• https://github.com/dlt-hub/dlt/actions/runs/8986556716/job/24682953543?pr=1334#step:10:185

Task

Make sure the CI is not failing. Investigate the cause of the exception. If it is not possible to fix the cluster, run the Qdrant in docker (see Weaviate for example: https://github.com/dlt-hub/dlt/blob/devel/.github/weaviate-compose.yml) and connect the tests to the dockerized instance.
