If buildx is not configured, RAUDI fails

[giper45]

Describe the bug

If you try to run RAUDI on a machine that has not configured buildx, the build fails. It is not relevant as we are focused on building the images, but it would be useful to add this information in README documentation in a clear way, as it could discourage people to contribute.

To Reproduce

• Install docker without configuring buildx
• run python raudi.py --sinigle <nameimage>
• Look at the errors:

Expected behavior Add in the README file that buildx should be installed before contributing to the project.
