Extend git-config settings for git-sync usage

[adwk67]

Reported in https://github.com/orgs/stackabletech/discussions/20
The current implementation of git-sync with the airflow operator restricts a pass-through of git-config settings. This is because a) the root directory is set internally, and b) we may want to expose specific settings via custom resource fields to keep things declarative. However, it would add flexibility if the user can pass any valid config setting. This issue will allow valid git-config settings to be added to ones that are defined internally, plus clear documentation that indicates what is actively and/or passively supported (similar to the approach used with the spark-conf/spark-k8s-operator).

I'll close this as it was actually duplicated by issue #332 (fixed by PR #335), which documents what was changed.
