- Remove multiple single top-level (# H1) headings per file
- Use (# H2 and ###### H6) sub-headings for consistency
- Remove any trailing # in the headings
- This ensures proper table of contents rendering in MkDocs.
- Also removed RUN_NR_multiple_BWPs.md as it is moved to MAC usage
- The parser was incorrectly interpreting `</` as the start of an HTML closing tag, leading to a crash in mkdocs
- Replace with HTML entity to ensure it is treated as a plain text.
