Docker fix fails when tag not specified for image

Line 45 in 77dcaa8

tag := leftOfAt[2]

assumes that a tag is always specified. When it is not specified, the code fails.

Here is an example
https://github.com/onnx/onnx/blob/540c58b4fa622c99880bcd2ea086089cae56bc9d/.github/workflows/release_linux_x86_64.yml#L46

• We need to figure out how to fix an issue when the tag is not specified.
• Handle cases when the tag is not specified and not error out

Same issue here: fleetdm/fleet#10205

Files it missed:

• https://github.com/fleetdm/fleet/blob/main/Dockerfile
• https://github.com/fleetdm/fleet/blob/main/Dockerfile-desktop-linux (maybe not different issue?)
• https://github.com/fleetdm/fleet/blob/main/Dockerfile.osquery-perf (maybe different issue?)
