v2: 

- Also replace *.txt -> *.rst. I opted to place the full file names there, as this allows
  ./scripts/documentation-file-ref-check to check if those files gets renamed. It
  also helps if some Sphinx would later convert those to hyperlinks (with was
  already discussed at linux-doc ML, although not implemented yet).
