labels don't follow oci annotations spec

**Describe the bug**

image labels should follow [the spec](https://github.com/opencontainers/image-spec/blob/main/annotations.md
)
for example com.github.containers.toolbox should be io.github.containers.toolbox becuse com.github is for github's use io.github is for user like (dead link you don't use github pages)

**Expected behaviour**
image should follow the oci annotations spec

**Actual behaviour**
total anarchy

**Steps how to fix the behaviour**
use this label expression (read it and the spec to be sure you want this esp the license)

```dockerfile
LABEL io.github.containers.toolbox="true" \
com.redhat.component="$NAME" \
org.opencontainers.image.title="$NAME" \
org.opencontainers.image.version="$VERSION" \
org.opencontainers.image.description="Base image for creating Fedora toolbox containers" \
org.opencontainers.image.authors="Debarshi Ray " \
org.opencontainers.image.source="https://github.com/containers/toolbox/" \
org.opencontainers.image.licenses="Apache-2.0" \
