iterate through tags of repo

In some projects, the releases are represented b tags only (eg. jhy/jsoup).
for more info see https://github.com/bcit-ci/CodeIgniter/issues/3421.
In these examples, the releases are empty.
as stated, the (unreliable) way to get the same goal is to iterate through the tags.

My question is:
How can I iterate through the tags of a repo?
