Spring-ai BeanOutputParserTest fails on Windows due to platform specific line endings

The template in BeanOutputParser contains \n line endings, the generated schema contains \r\n line endings, and the assertions in BeanOutputParserTest contain \n line endings.

This causes BeanOutputParserTest to fail when run on Windows 11 either as part of the build or by itself.

Since I'm working on both MacOS and Windows 11 I figured I'd file an Issue and submit a PR to fix it.
