Work around Terraform Provider bug when deleting permission sets

[Nuru]

Describe the Bug

When trying to delete/destroy a permission set, Terraform/Tofu fails with an error like

Error: waiting for SSO Permission Set (arn:aws:sso:::permissionSet/ssoins-xxx/ps-xxx)
provision: unexpected state 'FAILED', wanted target 'SUCCEEDED'. 
last error: Received a 404 status error: Permission set provision not found in AWS account 123456789012.

This is due to a known bug in the AWS Provider, with a known workaround.

Expected Behavior

Destroying permission sets should proceed without error

Steps to Reproduce

• Create a permission set
• Assign it to groups and accounts
• Delete the permission set and assignments
