Code Review

This pull request updates the JSDoc and example code in both regional and global parameter version rendering samples to indicate that the parameterVersionId can accept an alias like 'latest'. The review feedback suggests using single quotes for the alias in the JSDoc to maintain consistency with the repository's coding style.
