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- options.md: add Windows to defaults list, remove outdated tip about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
