[10.0.101] Fix the SR10 test failures

[TamilarasanSF4853]

This pull request makes a minor UI adjustment to the Issue35826 test case in the host app. The only change is to the padding of the pickerAvailabilityLabel, increasing the top padding to improve visual spacing.

• UI Adjustment:
  • Increased the top padding of pickerAvailabilityLabel from 0 to 150 in Issue35826.cs to prevent the label from being hidden behind the status bar, which could cause a timeout exception during the test.

Removed the unnecessary changes added by Copilot that caused an exception in the test, while retaining the original test and the fix from #36769

Fixes: #37746
