Note from handover call with @Silvan_WMDE :
The two patches currently undo the code added in the following patches:

nan-hani is merged, stalling this on the campsite board until the additional language codes are approved by LangCom.

This seemed to be ready for verification, as it has already ran a couple of times:
https://dumps.wikimedia.org/wikidatawiki/entities/20210203/ and https://dumps.wikimedia.org/wikidatawiki/entities/20210210/.

Task Inspection note:
The list of languages without a translated language name is here https://gerrit.wikimedia.org/g/mediawiki/extensions/Wikibase/+/711874256d9d00d5cd3ed1e2d3e82391aaac735c/lib/includes/WikibaseContentLanguages.php#84

Task inspection hints:

• we presume that we will probably need to change the parser to allow the minus sign
• as an entry point it might make sense to start from the wbparsevalue API action
• also look at extensions/Wikibase/vendor/data-values/number/src/ValueParsers/DecimalParser.php, normalizeDecimal()

Task inspection note: we probably want to start with adding the browser_test to the test script in package.jsonand see what happens

After testing this again, multiple devs were able to run the browser test without issues. Closing as this seems to be resolved.

@Lucas_Werkmeister_WMDE's fixes this for data-bridge, I guess it would make sense to do this for the other projects too for consistency purposes. Moving back to To Do.

For verifying this locally:
add the following to your LocalSettings.php:
$wgWBRepoSettings['idGeneratorRateLimiting'] = true;
$wgRateLimits['wikibase-idgenerator']['user'] = [ 0, 60 ]; 1 per minute
$wgRateLimits['wikibase-idgenerator']['anon'] = [ 0, 60 ]; 1 per minute
$wgMainCacheType = CACHE_DB;

Moving to test (verification) as there are no objections from within the campsite to the comment above therefore no further work is required here.

Task inspection note:

• on WikibaseRepo we should log to the general Wikibase channel (LoggerFactory::getInstance( 'Wikibase' );).
• the logger definition on the wmf-config side can be completely removed

Task inspection note: it might be possible to get the Lemmas by build the EditEntity result the way GetEntities does.
See https://github.com/wikimedia/Wikibase/blob/fa50e8941ca62e3c798fd6b4a949c2fa43b9f3cd/repo/includes/Api/GetEntities.php#L346 for more info.

As this is still occurring and the time box has been exhausted with no actionable outcome, moving this to test (versification) to consider what the best way forward might be.

Per Adam the next step could be 40% for Wikidata.org, in case we want to be extra cautious
