docs: recommend Josh workspaces

Workspaces are not the default filter when you clone a directory,
however we want them so we can have folders such as .tangled shared
between multiple workspaces. Therefore, we should recommend them for our
clone URLs

README.md

···
 be used to filter your clone:
 
 ```bash
-git clone https://git.freshlybakedca.ke/patisserie.git:/packetmix.git
-# Swap out "packetmix" at the end of the URL for whatever project you want to clone
+git clone https://git.freshlybakedca.ke/patisserie.git:workspace=packetmix.git packetmix
+# Swap out the "packetmix"es at the end of the URL for whatever project you want to clone
 ```
 
 If you need to push then, as with *tangled* normally, you are required to use
···
 to use SSH.
 
 ```bash
-git remote set-url --push ssh://[e-mail]/patisserie.git:/packetmix.git
+git remote set-url --push ssh://[e-mail]/patisserie.git:workspace=packetmix.git
 # Swap out "packetmix" at the end of the URL for whatever project you have cloned
 ```
