Code Inspection: Invalid destination for ''ADD''/''COPY'' commands

Reports invalid destination directories in ADD and COPY commands.

According to the Dockerfile specification, if multiple sources are specified, then the destination must be a directory, and it must end with a slash '/'. Otherwise, Docker build will fail.

Examples:

# all the commands below will fail
ADD textA.txt textB.txt relativeDir
ADD ["binaryA.jar", "binary2.jar", "destination"]
COPY text3.txt text4.txt /absolute/path

After the quick-fix is applied:

ADD textA.txt textB.txt relativeDir/
ADD ["binaryA.jar", "binary2.jar", "destination/"]
COPY text3.txt text4.txt /absolute/path/
