Updated closed-issue-message + stale-issue-cleanup version

[alikulka]

A new release for the closed-issue-message action has been made. The workflow now uses v2 which should fix the action failing.

Hey, thanks for opening this PR!

Is there a reason we changed from using a SHAs to tags?

Using SHAs
If you need more reliable versioning, you should use the SHA value associated with the version of the action. SHAs are immutable and therefore more reliable than tags or branches.

Source: https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/using-pre-written-building-blocks-in-your-workflow#using-shas

We should be able to just update this to the latest SHA for the actions right?
