docs: add delvewheel to diagram, schema defaults, and docs (#2877)

Since delvewheel is now the default repair-wheel-command on Windows,
update all places where auditwheel/delocate were referenced but
delvewheel was missing:

- diagram.html: add delvewheel repair block for Windows (was grouped
  with ios/pyodide as optional dot)
- generate_schema.py: add Windows delvewheel default to the platform
  loop so schema.json includes the default
- schema.json: regenerated with Windows delvewheel default
- options.md: add Windows to defaults list, remove outdated tip about
  delvewheel being early-stage/optional, update examples
- contributing.md: add delvewheel to the tool list

-!!! tip
-    cibuildwheel doesn't yet ship a default repair command for Windows.
-
-    **If that's an issue for you, check out [delvewheel]** - a new package that aims to do the same as auditwheel or delocate for Windows.
-
-    Because delvewheel is still relatively early-stage, cibuildwheel does not yet run it by default. However, we'd recommend giving it a try! See the examples below for usage.
