Can't delete containers with dot in name

When trying to remove a container (local or remote) with a dot in the name, deletion fails:

```
Request URL: http://localhost:8002/api/automation-hub/_ui/v1/execution-environments/repositories/alpine684828.6764255192/
Request Method: DELETE
Status Code: 404 Not Found
```

the 404 is a HTML response.. "Using the URLconf defined in pulpcore.app.urls, Django tried these URL patterns, in this order:"

I think the failing match is `/api/automation-hub/ _ui/ v1/ execution-environments/ repositories/(?P<base_path>[-\w]+\/

[-\w]+)/ [name='container-repository-detail']` .. `\w` doesn't cover a dot. Or it could be a validation problem? (But right now, the ui, the api, and podman all allow me to create containers with dots.)
