emibcn/badge-action@v1.2.4 gets warning about using old @actions/core

[DavidCooperWCU]

The following warning happens when using the badge action:

Warning: 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/

This can be fixed by updating the version of @actions/core

Just in case anyone is waiting on this and the author doesn't get to releasing a fix, I replaced a simple usage with badgen.net.
