dev-manual: update references to Docker installation instructions

Update Docker installation URL on various plaforms, replacing
some URLs by the ones they now redirect to, renaming "Docker CE"
to "Docker Desktop" on Mac and Windows, and to "Docker Engine"
on GNU/Linux.

Stop mentioning "Docker Toolbox" which is now deprecated and
replaced by "Docker Desktop" on Mac and Windows.
