Move Tika version and URL to seperate config file

[opensemanticsearch]

Move environment variables of Tika version and url to separate config file, so there is only one single source of truth for building all the different packages and images and we have not to upgrade multiple files on new Tika releases.

Done for build of deb packages by d23620e and opensemanticsearch/open-semantic-search@8923427
