Adding Docker image to container registry

Are there any plans on adding the AlphaFold3 container image to any container registry like DockerHub? I believe it could simplify the installation a lot for some users.

Would as a bonus also improve reproducibility.

## Example use case
Users of an academic HPC compute cluster running Apptainer/Singularity, set-up so that users can install their own containers. Currently they would have two alternatives:

1. Installation as recommended:
1. Install Docker on their own computer (possibly first need to install VM to install docker in)
2. Build image according to suggestions here
3. Convert to singularity/apptainer image
4. Transfer to cluster and hope that it works
2. Direct singularity install
1. Try to translate Dockerfile to Apptainer/Singularity definition file
2. Try building, if it doesn't work go back to 1

However, if you added it to a container registry the step would instead be:
```
apptainer pull alphafold3.sif registry.io/deepmind/alphafold3:latest
```
