Subject: [PATCH] CI: Updated GitHub workflows

Refreshed the workflow configuration to match the current GitHub-hosted
runner layout and the current Julia package maintenance guidance.

Split the macOS matrix into arm64 and Intel lanes, added an explicit
lts lane alongside Julia 1.6, limited coverage upload to one stable
Linux job, and updated the cache, Codecov, and formatter actions.

Replaced CompatHelper with Dependabot for Julia dependency updates,
following the current PkgTemplates default, while keeping GitHub
Actions dependency updates enabled.
