Pull in setup instructions as a submodule

[bkmgit]

The setup instructions are also used in the Shell novice lesson. Referring to the workshop template is a little confusing. Would you consider using a git submodule to allow them to be within the main lesson?

IMO, this is not a good solution because working with submodules is difficult even for people who are comfortable with Git. The problem arises because submodules by default will point to a single commit in the repository, but in a case like this, the lesson maintainers would much prefer to have them point to the HEAD of the repository, which is not straightforward (source: I've had to do this very thing for the lesson transition and it can be frustrating).

There has been discussion in the past about this, but not much capacity to address it, I'm afraid: carpentries/maintainer-RFCs#9

I'm closing this issue as it's out of scope for the lesson.
