cargo: Bump config to 0.14.0

Update `config` to the latest minor version.

The latest version of `config` adds more detailed error information that
require updates to snapshot tests. More significantly, environment
config variables are no longer case-sensitive[1]. Internally they are
down-cased, so we must adjust `test_command_args` to set lowercase
environment variables.

In addition, the newly added `config::Value::origin()` method exposes
the path of config files.
