ci(gitlab): refactor ci pipelines

merge build with test; merge release with deploy; use semantic-release

.gitlab-ci.yml

 # This GitLab runner configuration ensures every version of the SADE app is
 # working properly before making it public.
 #
-# Final versions of SADE (i.e. develop or master branches) that have been built
+# Release versions of SADE  that have been built
 # successfully are uploaded to DARIAH-DE's public eXist repository at
 # https://ci.de.dariah.eu/exist-repo/index.html where other projects can reuse it.
-#
-# Please make sure you have all necessary passwords set as secret variables.
-#
-# In case you're using SADE for an non-DARIAH-DE project, 'upload' should be
-# adapted or completely omitted.
-#
-# Environment variables used:
-# * ${EXIST_UPLOAD_PW}  - the password needed to push to DARIAH-DE's eXist repo
-# * ${FILENAME}         - the name if the XAR package created, e.g. SADE-develop-1-1-1.xar
 
-# a general image that contains everything eXist-db needs to run properly
