More "Learn more about this on the documentation" should be "in the documentation"
Opening this issue again (#13065), as there are two instances evident by grepping the codebase that weren't fixed:
#4629 rewrote some help page text to include the sentence:
Learn more about this on the documentation
It should read "in the documentation".
It is also incorrectly split into two sentence fragments, translated separately instead of a single sentence. This will result in bad translations.
»Learn more about this« »on the documentation«
