Depreciated commands

[sinyayadynya]

I'm getting this 2 warnings while running the 'publish' jobs:

Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: actions/checkout, actions/setup-node, cycjimmy/semantic-release-action, crazy-max/ghaction-github-pages, actions/checkout

The 'set-output' command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Also, it would be great if this example widget could be updated to React 18.
