feat: handle account removal with android.accounts.action.ACCOUNT_REMOVED

This commit introduces the handling of the `android.accounts.action.ACCOUNT_REMOVED` action.
The `AccountRemoveCallbackReceiver` now specifically checks for this action to ensure it's handling the correct intent.
The `isInvalidAction` method has been updated to use a direct string comparison against the constant `ACTION_ACCOUNT_REMOVED`, making the check more concise.
