docs: add command for ddevcd

[tyler36]

The Issue

I recently reset a WSL distro which required me to reinstall DDEV.
When I reached for ddevcd command I got an error:

$ ddevcd senju 
zsh: command not found: ddevcd
$ ddev -v      
ddev version v1.25.0

My Google skills found

• the blog announce of the feature
• with a link "tiny bit of one-time configuration" that displays the "Commands" page.
• searching on this page for ddevcd lead to "Note that this command can’t work until you make a small addition to your .bashrc, .zshrc, or config.fish."

The required "small addition" didn't appear obvious to me though.

How This PR Solves The Issue

This PR adds a hint to type ddev debug cd, which the required commands for bach, zsh, and fish.

I'm not sure the fix is right. You are actually in the ddev utility cd section. I think you're wanting to figure out how to use ddevcd ?

I was looking at the origin PR here which has ddev debug cd and worked.

ddev utility cd looks more approriate here though.

The canonical name of the command changed because people complained about debug. But it's still in my fingers.

The problem here may be that we just don't have a good place to describe this, except maybe the ddev.com PR that you kindly put up.

I'm sure we can figure out how to communicate this better, but I don't see how this helps. It already had exactly that text right below it. Is the problem that it was in a "code" section, so your eyes went right over it?

Please say again the problem you are trying to solve more generally. Is it that you lost ddevcd and couldn't figure out how to get it back? But that does come up right away in a search for "ddevcd" and takes you to https://ddev--8168.org.readthedocs.build/en/8168/users/usage/commands/#utility-cd

Wow. I'm sorry. My brain seems to be misfiring a lot today.

This PR doesn't seem approriate at all. I'm not sure why I was failing to comphrehend, it guess frustration and stress is catching up. 😞

We appreciate you all the time. I know there's a reason this didn't come through right, hopefully we'll figure out how to do better. But isn't ddevcd fantastic?
