Update cpp-linter action.

- Replace permissions from 'write' to 'read' to creat unified
  experience. PRs created from forks are not allowed to create PR
  comments, so setting 'write' permission works only for PR created from
  the local branches.
- Updated versions to the latest release versions.
- Use clang-format from 21 release.
- Use step-summary to report clang-format results instead of PR
  comments.
