Feature description

When banning a user, all roles are lost. (Discord fact)

Rarely, a user can be banned by mistake, either by discord replacing the user at the last moment, or user error.

We want to be able to see the roles a user has when they leave; mostly to give a complete picture of the user leaving the server, but also to make it easier to restore roles in the case of an accidental, incorrect, or misidentified ban.

Desired solution

Skyra can help by: when banning a user (or anytime a user leaves), the 'user left' message should include a list of all roles that the user had at the time; not only for restoring roles after an accidental ban, but also to give a complete picture of who is leaving the server.

This doesn't have to be a list of role mentions, just the names would be sufficient, however that's up to you.

Alternatives considered

Alternatively, this could be displayed only when a user is banned; however, I think it also makes sense for all users who leave.

Caching/storing previous roles to restore on rejoin seems like an unnecessary use of resources, when a log is more than sufficient.
