fix(gitlab-runner): Deploy fixed version of gitlab-runner

Version 0.61.0 introduced a new function in the register-runner script,
which fails to run with the image. The following error message is
thrown:

```
/configmaps/register-the-runner: 2: Syntax error: "(" unexpected
```

This was fixed by version 0.61.2.
