Testing regexp for latest updates strategy

[michalschott]

Describe the bug

Invoking argocd-image-updater test prints out:

...
# Check for the latest built image for a tag that matches a pattern
argocd-image-updater test nginx --allow-tags '^1.19.\d+(\-.*)*$' --update-strategy latest
...

So lets test it:

/usr/local/bin $ argocd-image-updater test nginx --allow-tags '^1.19.\d+(\-.*)*$' --update-strategy latest
DEBU[0000] Creating in-cluster Kubernetes client
WARN[0000] Invalid match option syntax '^1.19.\d+(\-.*)*$', ignoring  image_alias= image_name=nginx registry_url=
INFO[0000] retrieving information about image            image_alias= image_name=nginx registry_url=
INFO[0000] Fetching available tags and metadata from registry  application=test image_alias= image_name=nginx registry_url=
DEBU[0000] Using canonical image name 'library/nginx' for image 'nginx'  application=test image_alias= image_name=nginx registry_url=
INFO[0000] Found 0 tags in registry                      application=test image_alias= image_name=nginx registry_url=
INFO[0000] no newer version of image found               application=test image_alias= image_name=nginx registry_url=

Reason theres no images found is most likely other warning about invalid match option syntax, altho regex compiles correctly.

Am I missing anything there?
