Support Editing/Working with includes

[lweberru]

Describe the enhancement

For equal hardware I have separated an hardware specific include file and use the in all configs. An example is below.
Right now, the new ESPHome Device Builder (Beta) does not support the include. I can neither open the include file in the editor, nor does the main view allows somehow to see or edit the includes.
The compile and install works as expected.

Use cases

substitutions:
  name: esp32-3
  roomname: Bathroom
  staticip: 192.168.1.202

packages:
  # include central Base-Config
  common_base_file: !include includes/common_esp32_base.yaml

the include looks like:

# central config for all common ESP32 devices

esphome:
  name: ${name}
  friendly_name: ${roomname} ${name}
  name_add_mac_suffix: True
  platformio_options:
    build_flags: 
      - -Wno-maybe-uninitialized

packages:
  esphome.bluetooth-proxy: github://esphome/bluetooth-proxies/esp32-generic/esp32-generic.yaml@main

esp32:
  board: nodemcu-32s
  framework:
    type: esp-idf    

logger:

api:

ota:
  - platform: esphome
    password: ""

wifi:
  ssid: !secret wifi_ssid
  password: !secret wifi_password
  manual_ip:
    static_ip: ${staticip}
    gateway: 192.168.1.3
    subnet: 255.255.255.0
  ap:
    ssid: "${name} Fallback Hotspot"
    password: "xxxx"

bluetooth_proxy:
  active: true

esp32_ble_tracker:
  scan_parameters:
    interval: 1100ms
    window: 1100ms
    active: true

button:
  - platform: template
    id: button_stop_scan
    name: Stop BLE Scan
    on_press:
      then:
        - esp32_ble_tracker.stop_scan:
