fix(ci): add docs-only paths-ignore to container and coverage workflows

[josecelano]

Bug

Issue #1743 added paths-ignore rules to the CI "docs-only fast path" for
testing.yaml and os-compatibility.yaml, but two workflows were missed:

• container.yaml — the container build job
• generate_coverage_pr.yaml — the coverage report job

As a result, docs-only pull requests (e.g. PR #1760) were still triggering the
container build and coverage jobs unnecessarily, wasting CI minutes and
delaying feedback.

Fix

Add the same paths-ignore exclusions to both workflows:

paths-ignore:
  - "**/*.md"
  - "project-words.txt"

Also update the path-policy comment in docs-lint.yaml to accurately list all
workflows that carry the paths-ignore rule (replacing the stale list that
mentioned db-compatibility.yaml and db-benchmarking.yaml, which are already
scoped to code paths via paths: inclusion rules).

Changed files

• .github/workflows/container.yaml — Added paths-ignore to both push and pull_request triggers, plus path-policy comment.
• .github/workflows/generate_coverage_pr.yaml — Added paths-ignore to the pull_request trigger, plus path-policy comment.
• .github/workflows/docs-lint.yaml — Updated header comment to correctly list workflows that carry paths-ignore rules.
