Refs #32412 -- Adjusted Contributing Guide start page.

* Added headers emphasising Work on the framework vs Join the community
  sections, to raise the visibility of the community section.
* Added callouts to three main code/docs/translations areas, linking to
  respective start pages.
* Moved some Writing code specific content from the start page to the
  Writing code index. This clarifies the start page and adds content to the
  previously empty Writing code index.

+Work on the Django framework
+============================
+
+The work on Django itself falls into three major areas:
+
+**Writing code** 💻
+    Fix a bug, or add a new feature. You can make a pull request and see **your
+    code** in the next version of Django!
+
+    Start from the :doc:`writing-code/index` docs.
+
+**Writing documentation** ✍️
+    Django's documentation is one of its key strengths. It's informative
+    and thorough. You can help to improve the documentation and keep it
+    relevant as the framework evolves.
+
+    See :doc:`writing-documentation` for more.
+
+**Localizing Django** 🗺️
+    Django is translated into over 100 languages - There's even some
+    translation for Klingon?! The i18n team are always looking for translators
+    to help maintain and increase language reach.
+
+    See :doc:`localizing` to help translate Django.
