Godot Editor does NOT support Custom Android Build Templates written in Kotlin (build.gradle.kts)

[goldy1992]

Tested versions

• Reproducible in Godot 4.3 v4.3.stable.offlicial [77dcf97]

System information

Windows 11 Godot v4.3.stable.offlicial [77dcf97] Mobile

Issue description

In the Godot Source code: platform/android/export/export_plugin.cpp#L2552 I can see that the export_plugin is only checking for a build.gradle file to be present.

It should also check for build.gradle.kts in the case of custom Android Build Templates written in Kotlin.

Steps to reproduce

GIVEN

• A godot project that exports to Android.
• A custom build Android Build Template (e.g. build.zip)that:
  • Uses the same folder structure as the one provided by Godot.
  • Uses build.gradle.kts (i.e. Kotlin) to build as recommended by the Android Team
    WHEN
• The Godot Editor's Export dialog box is loaded to export to android.
  THEN
• Godot assumes an android template is not installed.
  

Expected Behaviour

• The project should still be exportable

Minimal reproduction project (MRP)

Any Godot Mobile Project with this example build template build.zip
