Quiet validation PR comments

[nubtron]

What does this PR do?

Adds quieter validation PR reporting for ddev validate all by marking validation report comments with hidden status metadata, skipping duplicate success comments, and allowing PRs labeled ci/skip-validation-comments to suppress validation report comments entirely.

Motivation

Validation reports should remain useful when they require attention or show recovery, but repeated successful validation comments add noise to active PRs. A label-based suppression option also gives maintainers an explicit way to keep PR conversations quiet while validations continue to run.

Changes

• Add hidden success/action-required markers to validation PR comments.
• Detect previous successful validation comments by metadata and skip posting when the current run also succeeds.
• Add ci/skip-validation-comments label detection from the pull request event payload.
• Delete existing validation report comments and post nothing when comment suppression is enabled.
• Keep workflow step summaries unchanged so each run still has local validation context.
• Add tests for success/failure/success transitions, metadata formatting, and label-based suppression.

Testing/Validation

• ruff check --fix ddev/src/ddev/cli/validate/all/__init__.py ddev/src/ddev/cli/validate/all/github.py ddev/src/ddev/cli/validate/all/orchestrator.py ddev/tests/cli/validate/all/test_command.py ddev/tests/cli/validate/all/test_github.py ddev/tests/cli/validate/all/test_orchestrator.py
• ddev --no-interactive test ddev -- tests/cli/validate/all/test_github.py tests/cli/validate/all/test_orchestrator.py tests/cli/validate/all/test_command.py
• Attempted ddev release changelog new fixed ddev -m "Allow PRs to suppress validation report comments with a label.", but it could not run in this detached worktree because origin/master is unavailable.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
