[PATCH] migration-guides/migration-4.2.rst: fix minor issues

[michael.opdenacker]

From: Michael Opdenacker <michael.opdenacker@bootlin.com>

- Underline fix
- Spacing fixes in bullet lists. Our standard
  is to use two spaces after "-", and a bullet
  list is supposed to be preceded by an empty line
  to be recognized.
