Nick Vigilante 44af8a1b56 docs: shorten the add-a-language install script copy and note apt reinstalls (#30376) ...

The "Add a programming language" guide embedded a full copy of the
install script that had drifted from the shipped Template Builder base
(it used `grep -q` partial matching, not `has_language`). The Final code
tab now shows an abbreviated excerpt (helpers plus the new Ruby branch)
so it can't drift again, and Step 4 and the "How does Coder install the
language you pick?" section use `has_language ruby`.

Also adds a short note in Step 4 that `apt-get` installs Ruby into the
ephemeral container, so it reinstalls on every start, while
home-directory installs persist. The persistent `~/.local` approach from
the ticket is not taught because it never landed on `main` (#28485 was
closed unmerged).

The `has_language` helper is present in the Template Builder base on
`main`. The older example template gets it in #30373. Refs DOCS-713.
