[Feature]: DeepL with glossary support

[kamaqnkatyqn]

Description

DeepL provides a feature to tweak the translation by using glossaries (and using one's own developer API which DeepL also provides free of charge for 500,000 characters per month).

It would be great to implement this feature in the POT translator.

For LLMs like Gemini Pro, also a glossary could be introduced. One would need to add a special prompt, asking Gemini Pro to use a glossary for translations and then insert the glossary entries as well in a prompt. I appreciate any help in creating a prompt like this...

Application Scenario

For certain specializations, professional translators have to correct AI output again and again. The glossary feature would help to make fewer corrections.
