I improved attributing original translation author while exporting translations from Weblate to language pack. So far all commits in language pack were authored by bot, so from perspective of language pack repository, there were no info about who made particular changes. You had to check it in commit history of main repository.
Since now original authors are attributed using
Co-authored-by trailer in commit message. Bot is still main author of the commit, but GitHub should detect and display you as an co-author of particular commit.
Detection of original author is really simple and may glitch in some edge cases (especially if you modify language pack repository directly), but it should work fine most of the time.
