Pages needing editing

[mjeronimo]

Reviewing the ROS 2 documentation, the following pages need editing:

Guides/Launch-files-migration-guide.html

• This page could use some basic editing

Related-Projects.html

• This page needs an editing pass for grammar.
• The page also needs an update. Navigation2, for example, is no longer supported by Intel.

Guides/RQt-Port-Plugin-Windows.html

• This page seems like someone's and could use an editing pass.
