bug#39359: [patch] TUTORIAL: Be accurate about "buffer" vs "file"; capitalize Dired. Four other trivial TUTORIAL patches

[Jorge]

Hello.  This trivial patch is my first patch submitted to a free
software project (not counting wiki edits), so please do not hesitate to
correct any mistakes (including the potential mistake of being too
nitpicky).  Now the commit message, followed by the patch:

TUTORIAL: Be accurate about "buffer" vs "file"; capitalize Dired

- Disambiguate "buffer" vs "file" after the section that explains
  buffers.
- Capitalize "Dired".
