Update node version and actions/core to 1.10.0

[jceresini]

Github is deprecating the set-output command in ~3 weeks, and this action will stop working. They are also deprecating node:12. It looks like this is unmaintained, but just in case you're willing to accept a PR, this should address both issues.

Here are the warnings that we've seen when using this action recently:

Node.js 12 actions are deprecated. Please update the following actions to use Node.js 16: jitterbit/get-changed-files@v1. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/.
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/

And some quotes from them:

We are monitoring telemetry for the usage of these commands and plan to fully disable them on 31st May 2023. Starting 1st June 2023 workflows using save-state or set-output commands via stdout will fail with an error.
...
Action authors who are using the toolkit should update the @actions/core package to v1.10.0 or greater to get the updated saveState and setOutput functions.

This PR just updates versions in package.json and the actions.yaml. Then I ran yarn package to rebuild dist/index.js

I need this change too.
