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

Use name conventions in .devcontainer

From git224 to git236

This script is used during the CI.

It is moved from .devocontainer to docker folder, probably this is not the correct place.

The build-install-openresty-voms.sh script is copied in /usr/local/bin instead ~/bin.

Deleted the addition of ~/bin from PATH env variable.

DEV_USER -> USERNAME
DEV_USER_UID -> USER_UID
DEV_GID -> USER_GID

See the best practise:
https://github.com/microsoft/vscode-dev-containers

All the file in assets used tu build the devcontainer are moved in library-script.

Modify the Dockerfile COPY directory
