### Apache Airflow version

2.5.0

### What happened

In [Airflow 2.4.0](https://github.com/apache/airflow/blob/main/RELEASE_NOTES.rst#airflow-240-2022-09-19), a new feature was added that added an option to mask sensitive data in UI configuration page ([PR](https://github.com/apache/airflow/pull/25346)). I have set `AIRFLOW__WEBSERVER__EXPOSE_CONFIG` as `NON-SENSITIVE-ONLY`.

The feature is working partially as the `airflow.cfg` file display only has [sensitive configurations](https://github.com/apache/airflow/blob/2.5.0/airflow/configuration.py#L149-L160) marked as `< hidden >`. However, the `Running Configuration` table below the file display has all configuration set via environment variables marked as `< hidden >` which I believe is unintended.

I did not change `airflow.cfg` so the value here is displaying the default value of `False` as expected.

The value for `expose_config` I expect to be shown as `NON-SENSITIVE-ONLY` but it shown as `< hidden >`.

### What you think should happen instead

As mentioned previously, the value for `expose_config` I expect to be shown as `NON-SENSITIVE-ONLY`.

Only the [sensitive variables](https://github.com/apache/airflow/blob/2.5.0/airflow/configuration.py#L149-L160) should be set as `< hidden >`.

### How to reproduce

Set an Airflow configuration through the environment variable and check on the Configuration page.
