DeepL: added Glossary and HTML functionality / ImageSharp: Vulnerability and Background fixes

[thornch]

DeepL: Added Parameter tag_handling and glossary_id defined by application.config:

• "translations.deepl.tagHandling": "html" // ability for translate HTML-Content (from Richtext-Editors)
• "translations.deepl.glossaryById": "{client-GUID-of-glossary}" // glossary lookup for specific translations
• "translations.deepl.glossaryByName": "{client-NAME-of-glossary}" // lookup glossary-id by glossary-name before translation

DeepL-Glossary: in case the glossary will update frequently, the glossary-id will change on every update. For keep the glossar functionality on updates, keep the glossary-name the same on each update and define the name instead of id. The lookup will take the first glossary in case the name existing more than once.

ImageSharp: Updated library Version and fixed missing background color:

• Updated SixLabors/ImageSharp from 3.1.5 to 3.1.7 - see GHSA-2cmq-823j-5qj8 for more details
• Added fix for background color - the background-parameter had no effect because pan-color was missing
