* Split the json_view feature page into sub-pages
The single features/json_view.md page grew to ~600 lines covering eight
topics. Split it into features/json_view/ with an overview page and
pages for ownership and lifetime, differences from basic_json, reading
values, generic code, editing, and images.
The new differences page collects what was spread over several sections
("What is the same", "What is different", "Duplicate keys", and notes in
the conversion and serialization sections) under one summary table, and
adds the parts of the basic_json interface a view does not have. The
other pages now link to it instead of restating the rules.
Internal links across the documentation point to the new pages.

* Docs: fix stale comments and trim repeated text in json_view pages
- fig-jsonview.js/.css: point the header comments at the new pages
- reading.md: views' strings are valid as long as the document (and a
borrowed source text), as lifetime.md says
- reading.md, generic_code.md: link to differences.md instead of
restating the member-order and repeated-key rules
- differences.md: drop the third mention of ordering comparisons, name
rbegin()/rend() in the iterator row
- exceptions.md: link editable documents to editing.md

nlohmann::json_editable_document
Defined in header <nlohmann/json_view.hpp>
using json_editable_document = basic_json_document<json, view_mode::editable>;
This type is an editable basic_json_document of the default
json specialization: in addition to everything json_document offers,
set and push_back change values after
parsing, without ever rewriting the source text — see Edits and
Editing a document.
Examples
??? example
The example below patches two fields of a small configuration document — changing one and adding another —
and dumps it back out with the member order and the spelling of the untouched number preserved, something a
plain [`json`](json.md) value cannot do.
```cpp
--8<-- "examples/json_editable_document.cpp"
```
Output:
```json
--8<-- "examples/json_editable_document.output"
```
