fix(org-babel): correct java structure-template language name

The `<java` Org Tempo template expanded to "#+begin_src javas", a typo for "java", so a Java source block came out tagged with a bogus language. I fixed the entry to "src java" and added a test that pins seven common aliases (bash, zsh, el, py, json, yaml, java) to their intended src language names, so the next typo in the template list gets caught.

+
+;;; Commentary:
+;; org-babel-config.el registers Org Tempo structure templates (e.g. `<el'
+;; expands to an emacs-lisp src block) by adding entries to
+;; `org-structure-template-alist' in org-tempo's :config.  A typo in the
+;; value expands to a bogus language name (a `<java' that produced
+;; "#+begin_src javas").  Requiring the module then org-tempo fires that
+;; config in batch, so this test pins the alias-to-language mapping for the
+;; common aliases.
