Fix broken Android CI due to broken BundleJsAndAssetsTask override (#…

…32194)

Summary:
Pull Request resolved: #32194

This Diff fixes the `test_android` CircleCI that is currently broken due to a faulty `BundleJsAndAssetsTask`
(that's my fault sorry for this).

The CI is failing with a `execCommand == null!` error message. The message is happening as the aformentioned
task is not correctly overriding `exec()` but just declaring a `TaskAction`. I'm fixing it.

Changelog:
[Internal] [Changed] - Fix broken Android CI due to broken `BundleJsAndAssetsTask` override
