chore(docs-check): remove the deleted grant-scoring workspace entry

[karagozemin]

Problem

The deploy-document checker still includes the removed grant-scoring example in its hard-coded workspace package list. The missing directory is silently ignored, leaving stale repository metadata in the checker.

Task

Remove the obsolete workspace entry and verify the deploy-document check still passes.

Acceptance criteria

• The checker no longer references the removed grant-scoring workspace.
• pnpm docs:check and its tests pass.
• No active workspace or documentation content is changed.

Suggested implementation prompt

Remove the obsolete grant-scoring workspace entry from the deploy-document checker, run the checker and its tests, and make no unrelated changes.
