The image.tag value is for previous version than the git tag

[stormmore]

The value of the image.tag is also for the previous version of the Nginx than the one mentioned in the Git tag, i.e. Git tag 1.5.1 has the image tag 1.4.0:

sigsci-nginx-ingress-controller/sigsci-values.yaml

Line 5 in 7ad4bdb

tag: "1.4.0"

Not sure if this is by design though. However it can cause confusion
