Chore: Suppress unqualified CodeQL admonitions

GitHub's CodeQL flags [1] those spots with "Unused global variable" [2].

Based on a suggestion [3], this patch attempts to use the
`advanced-security/dismiss-alerts` [4] GitHub Action recipe to provide
measures to suppress CodeQL flagging by using inline code annotations.
