fix: Merge arrays from same config key.

[MrMYHuang]

With these changes, electron-builder can merge extraResources from parent config and current conifg. For example:
common.json:

{
  "extends": null,
  "extraResources": [
    "common/*.files",
    "common.file"
  ]
}

specific.json:

{
  "extends": "common.json",
  "extraResources": [
    {
      "from": "specific",
      "to": ".",
      "filter": ["file.txt"]
    },
  ]
}

The merged config - dist/builder-effective-config.yaml:

directories:
  output: dist
  buildResources: build
extends: common.json
extraResources:
  - filter:
      - common/*.files
      - common.file
  - from: specific
    filter:
      - file.txt
files: []
electronVersion: 16.2.3

@MrMYHuang this PR seems to have caused a bug in the latest version, can you please take a look?
A config of:

extraFiles:
  - from: node_modules/node-mac-permissions/build/Release
    to: MacOS
    filter:
      - '*.node'
  - from: node_modules/electron-deeplink/build/Release
    to: MacOS
    filter:
      - '*.node'

The effective electron-builder config shows it duplicated,

extraFiles:
  - from: node_modules/node-mac-permissions/build/Release
    to: MacOS
    filter:
      - '*.node'
  - from: node_modules/electron-deeplink/build/Release
    to: MacOS
    filter:
      - '*.node'
  - from: node_modules/node-mac-permissions/build/Release
    to: MacOS
    filter:
      - '*.node'
  - from: node_modules/electron-deeplink/build/Release
    to: MacOS
    filter:
      - '*.node'

This doesn't seem to cause an issue with files, but it does cause it to try and double-copy when in extraFiles which then throws an error on my linux build machine (can't repro on my mac locally, didn't check windows.)

[MrMYHuang]

The effective electron-builder config shows it duplicated,

I can't reproduce it on Linux and macOS with electron-builder 23.0.9. I tested with extraFiles in both parent config and current config, and each extraFiles has two elements as your example with different "from" values.

Please revert this PR as your decision.

OMG, this BREAKING CHANGE messed up all my config inherits.

I wonder if this could be related to #7021.
