Operator ignores Thanos images specified in the CR

[4n4nd]

In my CR, I have tried setting the image for Thanos Components (Store/Compact/Receive/...) to quay.io/thanos/thanos:v0.20.1 or any other image but It always uses quay.io/thanos/thanos:v0.17.1.

I am not sure if this is relevant, but I see this in the Operator logs:
