Windows file path incompatibility

[C4J3]

Describe the bug

When updating containers hosted on Docker with Windows (WSL2) watchtower claims that windows file paths (D:\Docker\configs\containerName:/config) are invalid. This method of referring to directories is otherwise supported by Docker, docker-compose and external tools using them like Portainer so I'm not sure why watchtower doesn't like it but I also have no idea what I'm doing 90% of the time in Docker anyway so I can't say.

Steps to reproduce

1. Install Docker Desktop on Windows and enable WSL2 mode.
2. Set up and launch an outdated container with a windows volume mount such as:

...
volumes:
   - D:\Docker\configs\containerName:/config
...

2. Open 'wsl' (I search wsl in the start menu and open the not tux icon. Should end up in a terminal interface logged into root@<device name>.
3. Execute docker run -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --run-once.
4. Get normal output until time="<timestamp here>" level=error msg="Error response from daemon: invalid volume specification: '- D:\Docker\configs\containerName:/config:rw'".
5. Continue with update until output stating that container failed to update.
6. End up with container missing until remade externally (note that the image pull works fine so manually remaking the container will have it updated.

Expected behavior

The arguments that were used to create the container be used and work when watchtower remakes it.

Additional context

I'm still feeling my way (blindly) around using Docker and using it under Windows is just a cruel and unusual punishment I've inflicted upon myself at this point so I'm probably missing a lot of information I should have here. If there's anything important I can provide please ask but I don't know how to create an outdated environment to test things with so any if I need to test things I'll need a basic explanation on how I can do so.
