Electron-builder: Cannot use afterInstall to run tpl scripts anymore inside linux target build

[darkwave]

• Version:
  19.27.3
  

• Target:
  linux
  
  afterInstall option inside package.json build section does not work anymore (it was working a few weeks ago)

"build": {
    "appId": "com.codemotionkids.mbotjr",
    "linux": {
      "target": "deb",
      "afterInstall": "after-install.tpl",
      "category": "Education"
    },

I get this error:

Error: Configuration is invalid.
 - configuration.linux should be one of these:
   object { artifactName?, asar?, asarUnpack?, category?, depends?, description?, desktop?, executableName?, extraFiles?, extraResources?, fileAssociations?, files?, forceCodeSigning?, icon?, maintainer?, packageCategory?, publish?, synopsis?, target?, vendor? } | {
     "type": "null"
   }
   Options related to how build Linux targets.

   Details:
    * configuration.linux has an unknown property 'afterInstall'. These properties are valid:
      object { artifactName?, asar?, asarUnpack?, category?, depends?, description?, desktop?, executableName?, extraFiles?, extraResources?, fileAssociations?, files?, forceCodeSigning?, icon?, maintainer?, packageCategory?, publish?, synopsis?, target?, vendor? }
    * configuration.linux should be null:
      {
        "type": "null"
      }

How to fix:
1. Open https://electron.build/configuration/configuration
2. Search the option name on the page.
  * Not found? The option was deprecated or not exists (check spelling).
  * Found? Check that the option in the appropriate place. e.g. "title" only in the "dmg", not in the root.

Please move afterInstall to deb:

"build": {
  "appId": "com.codemotionkids.mbotjr",
  "linux": {
    "target": "deb",
    "category": "Education"
  },
  "deb": {
    "afterInstall": "after-install.tpl"
  }
}

Sorry that it was not a breaking change.
