Now the alias should be used as:

    git mr upstream 5

To check out a MR number 5 from the upstream remote, into a `mr-upstream-5`
local branch.

Also clarify that the `5` in the merge request is the number shown in GitLab.

The previous way was put under the
"By modifying `.git/config` for a given repository" section. The
disadvantage is that one has to modify `.git/config` for each repository
that one uses. The new way was put under the "By adding a git alias"
section. One has to create this git alias once, and then it will work
from any repository, without having to modify `.git/config` over and
over again.
