Using image:tag for input results in invalid artifact names

Using image:tag for input results in invalid artifact names.

Error: Artifact name is not valid: `<redacted>-python:3.9.spdx.json`. Contains the following character:  Colon :
          
Invalid characters include:  Double quote ", Colon :, Less than <, Greater than >, Vertical bar |, Asterisk *, Question mark ?, Carriage return \r, Line feed \n, Backslash \, Forward slash /
          
These characters are not allowed in the artifact name due to limitations with certain file systems such as NTFS. To maintain file system agnostic behavior, these characters are intentionally not allowed to prevent potential problems with downloads on different file systems.

This seems to be a limitation with GitHub workflow artifacts, I'm not sure it's something we can change/fix. Did you have any suggestions?

I'd be satisfied with the default artifact name being used for images too.

Is there a workflow step definition you could provide that reproduces this? Are you specifying the artifact-name with the image:tag format? If so, just use a different artifact name.

If the action is generating the name, it replaces all the special characters from the image value, including : with underscore (_).

E.g. if I specify localbuild/testimage:latest, the artifact name is: localbuild-testimage_latest.spdx.json

unfortunately, I'm unable to reproduce on public github. we have an artifactory acting as a proxy for docker hub as described here https://www.jfrog.com/confluence/display/JFROG/Docker+Registry. The image I was using registry.domain.com/python:3.9 breaks things. I can workaround it by specifying the artifact-name. thanks for looking into this.
