Update modules-known-issues.md

There are no more known issues for the module:
"Simple OAuth / OAuth 2.0
Issue: The module requires a very specific set of permissions for the folder and the keys to be uploaded. Using Private or non-standard filepaths won't work. It is not possible to change these in LIVE or TEST environment.

Solution: You can try to patch the permission check in the module. The alternative is to use off-site key management tools like Lockr"

The module now works without a workaround.

Refer to the [module source code](https://git.drupalcode.org/project/search_api_solr_date_sort/-/blob/7.x-1.x/includes/service.inc) for examples.
 
 1. Implement the `hook_search_api_service_info_alter()` function in your custom module's `.module` file and add your class into a configuration array. Refer to the [developer documentation](https://www.drupal.org/node/1999396) for details. Ensure that your [module's weight](https://www.drupal.org/docs/7/creating-custom-modules/howtos/how-to-update-a-modules-weight) is gereater than that of `search_api_solr_date` and `pantheon_apachesolr`.
