Update core library to fix output deprecation and add additional example

[jrich523]

Question

It looks like there is a deprecation warning for the output which is fixed in the newer core library.
https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

also it would be cool to provide a conditional example..

- name: Language Check
      id: lang-check
      uses: austenstone/list-repository-languages@main
- name: Validate Language
      if: contains(steps.lang-check.outputs.languages,'Go')
      run: echo "found Go!"

thanks
