More helpful Stata string length error.
The current error string when trying to write a string longer than 244 characters does not point users toward a solution that already exists: using the `version=117` parameter.
xref #23564 
- [x] closes: no issue that I see
- [x] tests: not needed; error string change only
- [ ] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [ ] whatsnew entry: too small a change?
