Remove-AzAppServiceEnvironment exits with NotFound error sometimes, but actually the target ASE is removed

### Description

I am using Powershell and Remove-AzAppServiceEnvironment to remove App Service Environment.
I tried this Module (Remove-AzAppServiceEnvironment) several times and found that sometimes it exited with NotFound error but actually the target ASE is removed. I mean, for example, if I try 5 times, probably 4 successes and 1 NotFound error.

Since I created an automated process to run this command, it is very confused that if it exits with NotFound error. Could you please fix the issue?
**Please see my debug logs for details.**

### Issue script & Debug output

### Error output

_No response_

Start at the Remove-AzAppServiceEnvironment cmdlet in Az.Websites and reproduce the DELETE followed by the long-running operation status request shown in the debug log. Confirm that a completed deletion is not reported as a failed NotFound operation, and verify the behavior with an automated removal run.
