Fix corpus table column headers and remove irrelevant CI columns

Changes:
- Created addCorpusTableHeader() with correct column names:
  Documentation, Repository, License, Issues
- Changed addCorpusTable() to use addCorpusTableHeader() instead of
  generic addTableHeader()
- Removed Doc CI and Core CI columns from addCorpusTR()
- Reduced table from 6 to 4 columns
- Updated addEmptyRow() to addEmptyRow(4) to match column count
