fix: Remove / when repoSubPath is not defined

[afranzi]

What issues does your PR fix?

• This PR aims to fix the issue with Airflow 2.10.x where the scheduler compares the dag filelocation with the dag_folders path. The main issue is that the dags_folder setting ends up being /opt/airflow/dags/repo/ when the repoSubPath is empty, when the correct one should be /opt/airflow/dags/repo without the final slash. Otherwise the DAGs will disappear from the UI 🫠 .

The airflow code messing up with us is this one.

What does your PR do?

This PR makes the captures when the repoSubPath is not define in the values since the dags are already present in the root git folder

Hello @thesuperzapper :)
Once you have time could you take a look into this PR? Right now is blocking us to update to the latest airflow version 🫠

On another note, this issue is also linked to this Airflow PR, since both needs to be merged to work properly in airflow 2.10.

@afranzi in my testing, this does not fix the issue dags disappearing when using git-sync in Airflow 2.10.1.

It seems that Airflow 2.10.2 has reverted the problematic change. See the discussion in apache/airflow#42111, and the revert in apache/airflow#42220, so I suggest using 2.10.2 if you already upgraded.

Given this, I will close this issue and put a warning not to use 2.10.1 with the chart on the version matrix.
