IntuneDeviceConfigurationCustomPolicyWindows10: Decrypted OmaSettings cannot be applied to other tenant

[ricmestre]

Description of the issue

I added support to decrypt encrypted OmaSettings for IntuneDeviceConfigurationCustomPolicyWindows10 on #4059, nevertheless I forgot to change the property isEncrypted to $False if the setting was actually able to be decrypted, this leads to have the decrypted value in the blueprint but still mention that isEncrypted is $True so that config cannot be applied to other tenant.

The fix is to simply set isEncrypted to $False if the setting could be decrypted.
