docs: fix remaining stale repr()/slice examples missing maiden

Six repr() examples in customize.rst (Hon Solo x2, dean title x3, the
suffix-attribute-list example) never got the maiden: '' line every
real HumanName.__repr__() now emits -- these predate the maiden field
and are unrelated to the nickname-delimiter sections this feature
actually touched, so they were missed. Also fixes usage.rst's
name[1:-2] slice example, which needed to become name[1:-3] once
_members grew by one (the corresponding test_python_api.py::test_slice
update was already made in this branch; the doc example was not).

Verified via sphinx-build -b doctest: total failure count across docs/
drops from 21 (after the earlier usage.rst-only fix) to 15, with no
remaining maiden-related mismatches. The rest are pre-existing
cross-example CONSTANTS state leaks already documented in AGENTS.md's
doctest gotcha, unrelated to this change.

Found by review agents auditing PR #199.
