Adds 2023 Mac mini to Supported Devices

[alexsmbaratti]

• Adds the 2023 Mac mini to Supported Devices section under M2 chip
• Adds the 2020 Developer Transition Kit for Apple Silicon to Supported Devices section under A12Z Bionic chip
• Fixes the 2022 Apple TV 4K Generation Number (mislabelled as 7th gen)
• Currently holding off on adding MacBook Pros with M2 Pro/Max chips
  • These models seem to have the same Neural Engine as the M2 chips at 15.8 trillion operations per second
  • Not sure how we want to handle M-series chip variants
  • A12 Bionic, A12X Bionic, and A12Z Bionic all have their own section despite sharing the same Neural Engine
  • The 2021 MacBook Pro models with M1 Pro/Max chips haven't been documented yet either
    • See #17 for an example
