Using a tag AND latest brokes the workflow

[jtama]

Summary

When using the action with tag_with_latest: true and tag: toto, the action seems to produce a multi-line output. The action is then considered as failed even thought it's not with the following message :

Error: Unable to process file command 'output' successfully.
Error: Invalid format 'myprivateregistry myimage:latest@sha256:d8d07c55b7ba2d51bc07971c1ae68c632cf13c651a7d0ad5453b395364c2d6fc'

The action works fine if only one tag is produced.

Version

at least 0.11.0 and 0.12.0.

This problem is resolved using the multiline output as described by that link in entrypoint.sh:

echo "image-tag-digest<<EOF" >> $GITHUB_OUTPUT
echo "$(cat /kaniko/image-tag-digest)" >> "$GITHUB_OUTPUT"
echo 'EOF' >> $GITHUB_OUTPUT

in fact they use the same technique just a bit above in the code to output the docker config.json.

@aexvir any chance to get this merged in anytime soon via my PR? #70

Oops, sorry, will check this in a couple hours. Thanks for flagging it!

@jtama this issue should be fixed in the release @aexvir did earlier today.
