fix: automatically determine NiFi version create reporting task script

[dervoeti]

Description

Since we use custom versions now, the wrong NiFi version was passed to the script (1.28.1 instead of 1.28.1-stackable0.0.0-dev for example). Since it's a bit hard to determine the actual SDP version of the NiFi image in the operator and this is just needed for NiFi 1 which will eventually be deprecated, I decided to just let the script determine the NiFi version on the go. It still has the -v parameter, we could remove it but that would require the operator to not pass it as well. I decided to go the easy non-breaking way and just leave it in, even though it's not used anymore.

TIP: Running integration tests with a new product image

The image can be built and uploaded to the kind cluster with the following commands:

bake --product <product> --image-version <stackable-image-version>
kind load docker-image <image-tagged-with-the-major-version> --name=<name-of-your-test-cluster>

See the output of bake to retrieve the image tag for <image-tagged-with-the-major-version>.
