fix: exclude target directory from markdown linting

The markdown linter was incorrectly processing generated documentation
files in the ./target directory, causing linting failures on auto-
generated content that should not be subject to style checks.

Changes:
- Add ./target/* exclusion to markdown file discovery
- Update comment to reflect both terraform and target exclusions
- Maintains existing .terraform exclusion functionality

This ensures linting only processes source markdown files and ignores
build artifacts and generated documentation.
