Fix docs links and Python doctest golden sizes for edition-gated writer

- Qualify the DEFAULT_WRITE_EDITIONS intra-doc link in the editions
  module docs: links in the module's inner docs resolve at the facade's
  `pub mod` site, so unqualified links break rustdoc under -D warnings.
  Also move the stray "Logical Vortex data types." doc line back onto
  the dtype module.
- Update the file-size golden values in the Python write-options
  doctests: the writer's pre-populated ArrayContext is now seeded from
  the session's enabled editions, which changes the footer's encoding
  list and shrinks the written files by 40 bytes.
