Is gitlab intentionally blocking google from indexing pages?

I have found that projects exclusively posted on gitlab are not found on google search results. Only the older versions hosted in github apppear on google search.

This page seems to imply its the robots.txt file:

https://forum.gitlab.com/t/gitlab-com-free-repositories-dont-show-up-in-google-search-results/3120

https://gitlab.com/robots.txt

The following project is not indexed:

https://gitlab.com/arduinoenigma/enigmaz30simulator

Trying two strings found in readme.md returns no result

https://www.google.com/search?q="An+Enigma+Z30+Simulator"

https://www.google.com/search?q="EnigmaZ30Sim.ino"

Is this intentional? I would really love to see gitlab search results instead of github?
