Fix Play verification file generation

[timkimadobe]

Note

This change will bump the AEPSDK Gradle Plugin version from gp-3.4.0 to gp-3.4.1

Description

What changed

• Moved the call to generatePlayConsoleVerificationFile(..) from when AEPLibraryPlugin was applied to the project.afterEvaluate { … } block.

Caution

This approach makes it so that if you turn the flag on, you need the token locally to even build the project which may not be an optimal development experience

Why it was needed

generatePlayConsoleVerificationFile() depends on user-supplied DSL values:

• aepLibrary { enablePlayConsoleVerification = true }
• namespace = "com.example.sdk"
• GOOGLE_TOKEN / PLAY_CONSOLE_VERIFICATION_TOKEN

When the plugin executed at apply time those properties were not yet set
(the build script hadn’t been evaluated), so:

• enablePlayConsoleVerification was still false → file never generated.
• The expected “missing GOOGLE_TOKEN” error was never thrown, hiding
  configuration problems.

By deferring the generation to afterEvaluate we guarantee:

• The build script has already populated all extension fields.
• The verification file is generated (or a clear error is raised) whenever
  enablePlayConsoleVerification is true.
• Behaviour is now consistent whether the task is run locally or in CI.

Testing locally, now when the enablePlayConsoleVerification = true the process fails at the build stage with a missing token error as expected
