add info about pager on Windows

[ghost]

Let's add some info about using pager (less) on Windows.

This is important because of
iterative/dvc#2807

The solution should go

Maybe in dvc.org/doc/user-guide/running-dvc-on-windows? Linked to from dvc.org/doc/command-reference/pipeline/show and other appropriate places of course. Please open an issue on dvc.org repo for this!

@xliiv do you know have a suggestion on what pager we should recommend for Windows? Or does this issue require research? Thanks

p.s. some ideas in iterative/dvc#2815 (comment)

@jorgeorpinel i would recommend less, it's installed with git on which we rely, do we? at least, less is installed on my windows.

DVC doesn't absolutely require Git. You can run dvc init --no-scm and skip the versioning features.

Even if less is installed with Git on Windows, it's probably buried somewhere in the Git installation directory and hard to figure out on every system. Unless you can reliably figure this out.

What about https://chocolatey.org/packages/Less if not?
