BUILD-11388

[sonar-review-alpha]

Summary

Switches the shellcheck pre-commit hook from the gruntwork-io wrapper to the official koalaman/shellcheck-precommit hook, which includes shellcheck directly. This simplifies the CI pipeline by using the canonical source rather than a third-party wrapper. Also bumps shellcheck from 0.10.0 to 0.11.0 in mise.toml.

What reviewers should know

Review focus: The hook ID remains shellcheck, so no workflow changes are needed, but verify that:

• The hook runs successfully in CI with the new configuration
• The version bump (0.10.0 → 0.11.0) doesn't introduce unexpected linting changes in your builds

For local setup: Developers will need to run pre-commit autoupdate or manually clear their pre-commit cache (rm -rf ~/.cache/pre-commit) to fetch the new hook on their next commit.
