Downloading Git does not automatically download gitk on apt based systems

[Yash-Singh1]

Which download is failing?

When you download Git on an apt-based system.

Problem

This isn't a big problem but when you are downloading git on an apt-based system, it does not download gitk automatically. Just a little heads up.

Context

I am using Ubuntu. Add gitk to the dependencies list in Ubuntu.

Steps to Reproduce

Download Git on an apt-based system and run gitk.

This is outside the scope of git-scm.com; packaging decisions are made by individual packagers. In this instance, gitk is split out into its own package so that people can install Git without having to pull in tcl/tk. And at least on Debian, the git package has Suggests: gitk, so it is really up to the package manager to decide how to present Suggests, or whether to pull them in automatically. (You could file a bug with Ubuntu that it should be Recommends instead of Suggests, but I think the current level is intentional; Recommends is stronger and would generally imply installing gitk by default, which many people in server environments wouldn't want).

One thing we could do on git-scm.com is mention gitk more explicitly at https://git-scm.com/download/linux. I'd be happy to review a PR if somebody wants to work one up.
