That could have been fixed at the source, by enforcing a plural form even if English doesn’t need it (that’s what I would do in Firefox). That would trigger Pontoon UI for plurals.
With that said, why are you adding a special case for 0? According to CLDR, Esperanto has the same rule as English, so 0 should use “aldonitaj”.
sc-personal-added-by-you =

I think that would be the way to go. Most likely other locales would use
the plural forms for those strings if Pontoon suggested it.
How can I go about it? Those strings are inside Common Voice. I’m not
sure if I should file a bug report in Bugzilla or an issue in Github or …
