Improve formatting in Dockerfile

[KrappRamiro]

Resolves: None, its just a formatting PR

Problem

The Dockerfile:

• Does not comply with the Docker FromAsCasing build check
• Has inconsistent formatting for newlines in RUN instructions
• Has too long RUN instructions
• Has an empty continuation line in the ending of the file

Solution

This PR:

• In the FROM instructions, replaces as with AS to comply with the Docker FromAsCasing build check
• Aligns the lines in the multiline RUN instructions
• Splits long RUN instructions into multiple lines
• Removes the empty continuation line in the ending of the file
