"mantle import" relies on removed API

[nightcycle]

Describe the bug
It appears that mantle import is no longer functional due to what appears to be a Roblox removed API.

To Reproduce
The usage of this command:
mantle import --target-id 12345 --environment name

results in this output:

Loading project:
  ╷
  │  Loaded config file .\mantle.yml
  │  Selected provided environment configuration staging
  │  Loading previous state from local file .\.mantle-state.yml
  │  No previous state for environment staging
  │
  ╰─ Succeeded

Import target:
  ╷
  │  Importing experience
  │  Importing experience configuration
  │  Importing experience thumbnails
  │  Importing places
  │  Importing social links
  │  Importing products
  │  
  ╰─ Failed: Roblox error (410 Gone): {"errorCode":"UnauthorizedAccess","errorMessage":"This endpoint is no longer available.","field":null,"hint":null}

Expected behavior
I expect it to not error in the console and do the intended behavior

Environment

• OS: Windows
• Mantle Version: 0.11.18
