chore(linting): clean up cspell warnings

[jcfranco]

Related Issue: N/A

Summary

• adds custom dictionaries for
  • examples (dict-calcite-design-system-examples) and
  • cspell-dicts contribution candidates (dict-cspell-pending-upstream)
  • Spanish and Arabic words were explicitly added instead of using their respective dictionaries to keep linting speedy
• replaces alt lorem-ipsum text with original version
• adds patterns for common words
• explicitly ignores rule for test hex codes used in color-picker-related tests
• fixes cspell errors
• fixes duplicate test name errors

Next steps

Create follow-up issues to:

• contribute candidates
• update doc with guidance (e.g., use hyphens instead of creating compound words, use sequential letters/digits when adding random or long text, etc...)
• discuss and define process for keeping track of words
• improve config (e.g., scope rules/dictionaries to relevant paths)
• clean up custom dictionaries
