Old errors in Friulian

I am updating some translations in Friulian (fur). This locale was created a few years ago, with some errors that have been copied in the new releases and that I would like to fix.
These are mainly date formats, number separators (number_format_decimal_point and number_format_thousands_sep), and the two strings for wptexturize. Should I fix them in each and every WP release since 2018 or is there a way to fix just one and have them all corrected?
