Merge branch 'develop' into techdebt/5710-5711-binary-formats-cleanup

Conflicts: - include/nlohmann/detail/output/binary_writer.hpp: kept write_msgpack_unsigned() for both msgpack integer cases; it already reads the active union member, which is what develop's #5694 fixes in the old ladders - single_include/nlohmann/json.hpp: regenerated with make amalgamate Signed-off-by: Niels Lohmann <mail@nlohmann.me>
Deduplicate UBJSON/BJData signed-count handling, drop dead ndarray checks

-Before opening a pull request, check the documentation like the CI does:
-
-```shell
-make build -C docs/mkdocs          # strict build: fails on broken links, anchors, and structure problems
-make check_mermaid -C docs/mkdocs  # checks the Mermaid diagrams (requires Node.js)
-```
-
-A new API page also needs an entry in [`docs/docset/docSet.sql`](https://github.com/nlohmann/json/blob/develop/docs/docset/docSet.sql),
-the search index of the docset; `make build` reports missing entries.
