chore(ci): add missing container-tag/container-suffix and fix stale standards doc (#207)

Add container-tag and container-suffix parameters to all reusable
workflow jobs in ci.yml. Fix repository-standards.md: correct git hooks
path, replace direct markdownlint with vrg-docker-run -- vrg-validate,
remove stale --agent flag from vrg-commit docs, fix --linkage default
from Fixes to Ref.

Addresses vergil-project/vergil-tooling#1015, vergil-project/vergil-tooling#1013
