Adding indonesian language leads to admin tabs layout crashing in TabedTranslationAdmin

[flameai]

If you add Indonesian (Id) to LANGUAGES in Django and try to use TabbedTranslationAdmin there it looks weird

What's in the browser console? Maybe there's some errors?

It's clear in console log.
I spent my day and figured out the bug:

--- a/modeltranslation/utils.py
+++ b/modeltranslation/utils.py
@@ -80,7 +80,7 @@ build_localized_verbose_name = lazy(_build_localized_verbose_n
ame, str)
 
 
 def _join_css_class(bits: list[str], offset: int) -> str:
-    if "-".join(bits[-offset:]) in settings.AVAILABLE_LANGUAGES + ["en-us"]:
+    if "-".join(bits[-offset:]) in settings.AVAILABLE_LANGUAGES + ["en-us", "ind"]:

It seems you'v forgot to make reverse lookup for Indonesian here in utils.py
Unfortunately I cant make PR to this repo.
It would be nice you make this fix for new version.

Thanks in advance.
