How to test this PR?

1. check out this PR:

https://github.com/devfile/developer-images/pull/46/commits/ec3d8c079542e8d90661ba6e92fb228baf523e27

2. change the ubi8/Dockerfile so it's building from:

# https://quay.io/devfile/base-developer-image#^ubi8-
FROM quay.io/devfile/base-developer-image:ubi8-8d9dc15

3. get scripts:

cd /tmp; curl -sSLkO https://raw.githubusercontent.com/redhat-developer/devspaces/2f8fbbea472be0f2953cb8ce33d72dc3ccfc20dd/product/getLatestImageTags.sh
cd /tmp; curl -sSLkO https://raw.githubusercontent.com/redhat-developer/devspaces/2f8fbbea472be0f2953cb8ce33d72dc3ccfc20dd/product/updateBaseImages.sh
chmod +x *.sh

4. run an update of the Dockerfiles:

cd /where/you/have developer-images checked out/
/tmp/updateBaseImages.sh -b main -w `pwd` -f Dockerfile      -maxdepth 3 --no-commit --no-push  -x "latest|main|source" --latestNext ubi8-latest --sort-tags false -v

This is the error I don't let know how to work around -- the newer tag is found, but the "which one is greater?" check is failing:

#CURR_TAGver=ubi8; CURR_TAGrev=8d9dc15; CURR_TAGrevbase=8d9dc15; CURR_TAGrevsuf=8d9dc15
#LATE_TAGver=ubi8; LATE_TAGrev=13008af; LATE_TAGrevbase=13008af; LATE_TAGrevsuf=13008af
