#3350missing endpoints to bulk delete multiple collections/groups

Subject of the issue

While testing the latest testingimage (vaultwarden v1.27.0-729b5631 / web-vault v2023.2.0), I noticed that with the new consolidated view it is now possible to bulk delete collections and groups in the organization tab, however this does not currently work because the respective endpoints are missing.

Steps to reproduce

Create an organization and add two empty collections (if you have set ORG_GROUPS_ENABLED=true you can test the same with groups). Select both collections and click on Delete selected in the uppermost three-dot menu and confirm.

Troubleshooting data

The XHR request to DELETE <DOMAIN>/api/organizations/85435556-697e-4441-91b6-14486c9469c6/collections with data:

{"ids":["95bfdea9-70e7-4ee5-956d-ecd25f53a9d3","3d652f44-cd05-4772-8d82-c8df8e89f6d3"],"organizationId":"85435556-697e-4441-91b6-14486c9469c6"}

The request to DELETE <DOMAIN>/api/organizations/85435556-697e-4441-91b6-14486c9469c6/groups:

{"ids":["a99a1ede-bf09-44f3-8a39-9f5a2fd22d48","cf3b45fb-f553-4cb5-a437-0e89cd0f2e79"]}

As both endpoints are missing, they return the following response:

{"error":{"code":404,"description":"The requested resource could not be found.","reason":"Not Found"}}
