Configuration not updating for content language after saving it

Hello @Tanuj, this works as expected, actually with content language as 'sites default' and language alterable false, it is Default settings. and the form build checks if the configuration stored matches the default configuration then there is no need to keep this. if you make any changes to the default config other than (content_language: sites_default, language_alterable: false.) then it will save the settings.

changing the status, as this works as expected.

please check similar issue here https://www.drupal.org/project/drupal/issues/3378812#comment-15184658 🐛 "Content language and translation" form doesn't save "Custom language settings" data Postponed: needs info keeping this in review.

@Tanuj can you confirm #9 please.
