fix: change error_description to error-description

[mantariksh]

Problem

When there is an error during the MyInfo consent flow, e.g. if the user does not provide consent, MyInfo returns error-description (note hyphen) in the query params, as shown in the screenshots below. However, Mockpass returns error_description (note underscore).

Solution

Change error_description to error-description.

As I understand it, MyInfo v2 assumes that the /login endpoint still returns error_description. Given that NDI no longer supports v2 however, I think it's safe to make this breaking change
