Subject: [PATCH] erlang: update to 28.5

Upstream release 28.5 (2026-04-23), patch release for OTP 28.

Applications updated:
- erl_interface-5.7: new --{enable,disable}-use-embedded-3pp-alternatives
  configure option; allows using system zstd, zlib, ryu, openssl, tcl
  instead of bundled copies (default: zlib uses OS version if available)
- erts-16.4: fixed bug in enif_make_map_from_arrays for arrays with >= 33
  keys (duplicates could produce broken maps); fixed Unicode handling in
  erl.exe args_file on Windows
- mnesia-4.25.3: bug fixes
- ssl-11.6: bug fixes

Highlight: new "Secure Coding Guidelines" document added to Design
Principles describing how to write secure Erlang code.
