gitlab-runner: remove deprecated privileged value
According to https://gitlab.com/gitlab-org/gitlab/-/issues/379064 several
runner values fields are removed in favor of using runner.config
template.
The only value I found in our config is runner.privileged
. I removed the value and added
it to runners.config
template. This should also work according to
https://docs.gitlab.com/runner/configuration/advanced-configuration.html#the-runnerskubernetes-section.
