fix: upgrade vector and decrease log level to avoid spam

Vector is spamming us with messages concerning absent containers. Such messages include:

tutor_local-cairn-vector-1                  | 2022-10-07T13:09:27.053010Z  INFO source{component_kind="source" component_id=docker_logs component_type=docker_logs component_name=docker_logs}: vector::internal_events::docker_logs: Started watching for container logs. container_id=680c2bf183676caadee2c165b26493f90fb5d02cb15b9f2579a106fdd436f827

Or:

{“log”:“2022-10-07T07:19:17.839042Z INFO vector::internal_events::docker_logs: Started watching for container logs. container_id=a932d5916f9a1d1848224b71070591d16c813e83796d6850fa64b0a5f956d5ed\n”,“stream”:“stderr”,“time”:“2022-10-07T07:19:17.83961548Z”}

This issue has affected multiple users in the past. To address it, we first
tried to upgrade Vector, which did not help. Thus, we decided to reduce the
verbosity of Vector.
