If one tries to run the following command to generate documentation in French:

typedoc --out docs --entryPoints lib/index.ts --lang fr

He will get this warning message:

[info] The languages that translations are available for are:
        en
        fr
        ja
        ko
        zh

And the documentation won't be translated.

All the other languages work as expected.

Expected Behavior

According to the message, fr should be a correct value for the lang option.

Environment

• Typedoc version: 0.27.7
• TypeScript version: 5.6.2
• Node.js version: v22.13.1
• OS: Windows 11

fr shouldn't be included in that list as it has no translations, TypeDoc was incorrectly including the selected language in the list
