Microsoft Azure Connection: Service principal secret does not get masked when providing connection via URI environment variable

### Apache Airflow Provider(s) microsoft-azure ### Versions of Apache Airflow Providers ``` apache-airflow-providers-microsoft-azure==9.0.0 ``` ### Apache Airflow version apache-airflow==2.8.1 ### Operating System Ubuntu 22.04.3 LTS ### Deployment Official Apache Airflow Helm Chart ### Deployment details _No response_ ### What happened I set the connection as follows: ``` export AIRFLOW_CONN_AZURE_DEFAULT='azure://<sp-appid>:<sp-secret>?tenantId=<my-tenant>&subscriptionId=<my-subscription>' ``` As `sp-secret` is a password, I would assume it is masked from task logs. However, this is not the case. I see 2 possible reasons: - There is no concept of hostname (so no `@fqdn`), which the masking feature might filter on? - There are special characters in the password field. In my case, the following characters are used: `UPPERCASE, lowercase, ~ - _` ### What you think should happen instead The log should render: ``` AIRFLOW_CONN_AZURE_DEFAULT=azure://<sp-appid>:***?tenantId=<my-tenant>&subscriptionId=<my-subscription>' ``` just like it does with for example postgresql connection. ### How to reproduce Add the connection (does not even need to make sense) as environment variables: ``` export AIRFLOW_CONN_AZURE_DEFAULT='azure://<sp-appid>:<sp-secret>?tenantId=<my-tenant>&subscriptionId=<my-subscription>' ``` Create simple DAG to print environment variables ### Anything else I have tried adding a fake hostname `x` by modifying the string to ``` export AIRFLOW_CONN_AZURE_DEFAULT='azure://<sp-appid>:<sp-secret>@x?tenantId=<my-tenant>&subscriptionId=<my-subscription>' ``` This still prints the secret unmasked. ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md)
