Do not copy version file in makefile

[33Fraise33]

Hello,

in the ossmediator makefile you copy the version file before building the container.

OSSMediator/OSSMediatorCollector/Makefile

Line 10 in 1a6a2da

@cp ../VERSION .

This gives issues if you just want to manually build the container without using the makefile.

I would propose to update the docker build file and change the copy command:

OSSMediator/OSSMediatorCollector/Dockerfile

Line 12 in 1a6a2da

COPY ./VERSION ../.

to: COPY ../VERSION ../.

This is the same for the elasticsearchplugin.
