Deprecated function: strstr()

Confirming that using the patch `commerce_authnet-deprecated-function-strstr-3319388-2.patch` fixes the issue

I was getting the error on `/checkout/39118/review` page

I started running into this issue on my site when testing going from php 8.0 to 8.1 to prepare for D10. The patch fixes the issue for me too.
