Apache Airflow version

What happened?

In Airflow 3.0, I can create a variable which key contains slash character '/' .
However, once the variable created, I cannot call API to modify or delete it.
Also I cannot get its value via "get variable" API, but I can get by list all variables using "get variables" API

I think the problem is that the slash in variable key has been treated as URL separator, so the API return error.
Also due to above reason, the APIs which not require variable key in URL still work (like "create variable" and "get variables")

I also tried to escape '/' as %2F when calling API, but still no luck.
In such scenario, api-server log still show '/' instead of '%2F' in visiting log

What you think should happen instead?
