The crowdin GHA is still failing

Configuration file is invalid. Check the following parameters in your configuration file:
- The mapping format is the following: crowdin_language_code: code_you_use. Check the full list of Crowdin language codes that can be used for mapping: https://developer.crowdin.com/language-codes.

Sadly, this relates to issue #12116 which prevents me from upgrading my local Crowdin CLI version to 4.0+.

I haven't been able to figure out which custom locale Crowdin is failing on

Jotting notes.

Downgrading to CLI 3.19.4 involves GHA v1.20.4
