Dockerfile changes

[OlegPhenomenon]

Tasks:

• Update Dockerfile.

Problem

• When deploying a Dockerfile, an error pops up stating that it is not possible to install packages that are trying to install from the buster debian repository.

Solution

• Remove the repository name when installing packages, since the local repository list is copied during installation and is sufficient to install the required dependencies and packages.

How to test?

• Deploy the EPP Proxy using this dockerfile.
• Manually check that the system is working properly. How is the communication between the registry and the registrar?!
