Fix traefik_route library ID

[michaeldmitry]

Issue

Previous PR tried to publish a new library traefik_k8s.v0.traefik_route, but using an ID for an existing library traefik_route_k8s.v0.traefik_route.

Solution

Retrieve unique ID for this new lib using charmcraft create-lib traefik_route

Context

#403

you'll also need to reset libpatch to 0 or 1 as it's effectively a new library

I did that last PR! But it seems CI has overwritten it after the merge (auto lib update?)
Good catch!
