SetOutput is going to be deprecated

[p-hash]

When using this action in my project, I get following warning:

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/

Luckily caused by this line:

portainer-deploy-stack-action/src/main.ts

Line 51 in 2bb163f

core.setOutput('stack-id', stack.id)

The warning message references a blogpage, which suggests updating @actions/core package to v1.10.0 or greater to get the updated saveState and setOutput functions.

So, I think updating the dependency might fix the issue

PR #277 is already there to fix the issue
