Thanks, must have slipped :)
Can you replace this PR number with (334 i think) the vector update in the changelog?

Just FYI that 0.33.1 has been released but not saying that we need to upgrade again

I saw that the new Vector version and the corresponding Helm Chart are available on GitHub but it is not announced yet. However, the actual upgrade has to be done in the Docker image and operator-rs. This PR just fixes the integration tests to be in sync with the version used in the Docker image.

This is for consistency since i forgot to bump it here. Bumping vector to 0.33.1 is another discussion and should be done in the release issue or in the docker images.
