action inlined body 3 times upon failed release

Extracted from #140 to avoid it getting lost. Thank you for all your work on this action 🙇

Came from a CI run yesterday on the 9th of August which failed like in #140 .

❌ Too many retries. Aborting...
Error: Too many retries.

The result of this retrying seems to somehow have been that the body text got appended to the existing release, so we ended up with 3 release texts in the release. kube-rs/kube#620 has the full detail.

Note that I don't know if it's still an issue after your main fix, or if it is coupled to the the retry behaviour, just seems suspect.

It’s still and issue as far as I know looking into it in #145
