TST IntegerArray bounds error closing GH21796

[TAJD]

• closes Bounds checks for IntegerArray #21796
• tests added / passed
• Ensure all linting tests pass, see here for how to run them

Thanks for the pr @TAJD! Think the test failure is because the test assumes int64, but on 32-bit builds or windows, the default integer size will be int32. So I'd suggest just not trying to match as completely or could use numpy's platform int

Thanks @mzeitlin11 - hopefully by allowing 32 or 64 in the regex on the error message tests the required functionality.

this is fine, though the message actually is slightly misleading, you are actually trying to cast to a nullable type, but the underlying casting is bubbled up here.

so merging this, but would be neat to look into having a slightly more informative message here.
