Invalid username or password when connecting to Snowflake

### What would you like help with?

Following your DOC, trying to connect to Snowflake:
```
uri = snowflake://:@/?warehouse=
with adbc_driver_snowflake.dbapi.connect(uri) as connection:
...
```

It returns the error `invalid username or password`.
When I use the same properties (user/pwd/account/warehouse/db) in DB IDE (DBeaver, Datagrip), it works.

Is it possible that the above URI is not parsed as I expected and the wrong password value is sent to the server?
I tried other documented variants of the URI format, but I still got the same error.

Any advice, please?
