Fix issue analyzer workflow: add projects:write permission to GITHUB_TOKEN

The workflow was failing with "Could not resolve to a ProjectV2 with the number 7"
because GITHUB_TOKEN lacked the `projects: write` permission needed to access
GitHub Projects V2 (org-level) via the GraphQL API.

Added `projects: write` to both the top-level and job-level permissions so that
the GITHUB_TOKEN has the necessary scope to query and update the org project.
