Fix uploading unit test results action in GitHub workflow

[nenorbot]

In this commit I disabled uploading unit test results, as this action was failing the build. You can see an example of such a failed build here: https://github.com/AppsFlyer/pronto/runs/5107634173?check_suite_focus=true

The impact is that the repo's test coverage badge is out-of-date 🤷

The specific error is:

2022-02-08 10:40:28 +0000 - publish -  INFO - creating check
Traceback (most recent call last):

My guess it's an issue with the GITHUB_TOKEN secret? Maybe it's not injected into this repo?

This was supposed to be a temporary measure but since I'm no longer a member/admin of this organization I can't look into it myself. However, this used to work and all I know at this point is that it broke somewhere between 2021-11-29 and 2022-01-31.

/cc pinging @yonatane -- sorry for waking you, but maybe you know where to redirect this issue internally at AF, to spare this issue from /dev/null

AFAIK this stopped working when AF started using the internal single sign-on solution, which messed up the permissions of the GitHub bot.

I've implemented a solution to a similar problem here: AppsFlyer/aerospike-clj#57.
I'll make some time and create a similar solution here as well 👍
