test: Add golden fmt file for safe_integer_conversion

Adds the `safe_integer_conversion.jsonnet.fmt.golden` file containing
the expected output from `jsonnetfmt`. This resolves the formatting
test failure for this file in `run_fmt_tests.sh` by providing an
explicit golden output for comparison, accounting for minor spacing
differences introduced by the formatter.
