Update workflows, CODEOWNERS, and config files (#1759)

Removes @thedaviddias from CODEOWNERS, clarifies copilot instructions to avoid deprecated TypeScript features, and updates dependabot.yml to group GitHub Actions updates and limit open PRs. Adds a workflow for accessibility alt text checks and introduces a .npmrc file with lockfile version and registry settings.
