commit 23c35dae297d2eecd13e17118a547761314a578d
from: Omar Polo <op@omarpolo.com>
date: Thu Jun 15 10:47:28 2023 UTC

change got_get_repo_tags' limit argument to size_t

The function already carefully avoids wrapping around zero.  While
here add a sanity check for limit == 0, like what was previously done
for got_get_repo_commits().
