API naming for issue scope
Description
Most of the API uses snake_case for Parameter naming. However, the scope in issues uses kepab-case.
It might be usefull to align this param with other values of the api.
Proposal
To allow devs to react one might first add the scopes created_by_me and assigned_to_me whilst deprecating created-by-me and assigned-to-me. The deprecated ones could then be removed in a future major version.
