i dunno why miri gives us a different error message, but oh well

Soryr -- looks like I missed htis one and merged an alternate fix from @bit2swaz instead

• fix(arrow-schema): stop asserting on unstable TryFromIntError message in tests #10433

The good news is the fix was the same, so I will close this PR

Thank you @Jefffrey and @Phoenix500526
