Here is what you can try. Since file systems, at least in Unix- and Linux-like systems (including macOS), file owners are a number, not a name. Various tools such as ls will translate the number into a name for convenience, but it is still just a number. Your user gitlab-runner in the container, and the user roggerfernandes on the host system, have the same UID. You can find the numeric ID by running the id command.
Here it is on my laptop (reformatted a bit for readability):
uid=501(dan) gid=20(staff) groups=20(staff),12(everyone),61(localaccounts),
Here you see at the beginning my UID is 501.
You can also run this command with a username, e.g. id gitlab-runner inside the container.
docker exec testes_cashlink id gitlab-runner
So when the user in the container owns a file, it is stored as a numeric ID (quite likely 1000, a common default). When you look on your host system, the mechanism that translates the number into a username just has a different username in its result than you would see inside the container.
If you need a specific user ID inside the container, you need to modify your Dockerfile so that when creating the user, you specify its uid. For example:
RUN useradd -u 1005 <other options> gitlab-runner
I hope the above information would be helpful for you.
