Add ignored_words option to HardCodedString linter

[krzyzak]

Adds support for custom translation exceptions via configuration. Users can now specify additional strings that should be exempt from translation requirements, alongside the default NO_TRANSLATION_NEEDED list. This is useful for:

• Brand names
• Custom HTML entities
• Project-specific terms
• Any strings that shouldn't trigger translation warnings

Usage example:

linters:
  HardCodedString:
    ignored_words:
      - MyBrand
      - "§"
