Add a new field within the profile PostReplace

[psmits1567]

Currently two auto translators are implemented DeepL and OpenAI. They do not give perfect translations, but that could be improved by adding a function that replaces words from key pairs stored within the profile of the user.
Steps to perform

1. Read the field PostReplace when page is opened.
2. After fetching the suggestion from OpenAI or DeepL, check the translation if it contains a word from the PostReplace field.
3. If present replace the word before presenting the suggestion.
4. If not present use the suggestion provided.

Example key pairs:
gemeenschap,community
alsjeblieft,
alstublieft,
kenmerk,attribuut

If the second part is empty remove the word from the translation.
