fix(eslint-plugin-react-compiler): support v9 context api

This change fixes a gap in the plugin's support of eslint v9.  In one place that it's using the SourceCode api, it's correctly considering v9's api.  But in the other place where SourceCode is used, it's only using the legacy api, which was removed in v9.
