Added voms-clients-java

gitlab-ci and readme need to be updated

Specify the correct location of the nginx-httpg_no_delegation.patch file in the script for installing openresty-voms in the devcontainer

Use both provide-deps.sh files in devcontainer:
 * provide-CI-deps.sh install the deps for CI
 * provide-dev-deps.sh install the remaining deps for the devcontainer

Before this update, provide-CI-deps.sh was a subset of provide-dev-deps.sh

To distinguish the differet provide-deps.sh in the same folder, one for the CI container, one for the devel container
