Pattern: Use of deprecated MAINTAINER

Issue: -

Description

The LABEL instruction is a much more flexible version of this and you should use it instead, as it enables setting any metadata you require, and can be viewed easily, for example with docker inspect.

Example of incorrect code:

MAINTAINER SvenDowideit@home.org.au

Example of correct code:

LABEL maintainer="SvenDowideit@home.org.au"
