Fix stale bot cache issue by adding actions:write permission

[tpantelis]

Summary

This PR fixes a caching issue in the stale workflow where issues are being perpetually skipped with the message "skipped due being processed during the previous run".

Problem

The stale workflow was lacking the actions:write permission needed to delete/update the cache between runs. Without this permission:

• The stale action creates a cache of processed issues
• It cannot delete or update this cache in subsequent runs (403 error)
• Issues get stuck in a "perpetually processing" state

Solution

Add actions:write to the job permissions in .github/workflows/stale.yml.
