v1.23.0

This update pulls in Erlang/OTP 26.0 and Buildroot 2023.02.1. For the Buildroot
portion, most projects that work with nerves_system_br v1.22.x shouldn't need
any changes with this update, but please review the Buildroot release notes.

• Upgrade notes

  • The default TERM setting changed from vt100 to xterm-256color. In the past,
    this didn't really matter. With OTP 26, the TERM setting starts being used
    so applications that use the terminal may change how they render.
  • OTP 26.0 comes with a multiline editor. At the time of this release
    multiline editing didn't work with ssh so it's currently disabled.

• Package updates

  • Erlang/OTP 26.0
  • Buildroot 2023.02.1. See the release notes for Buildroot 2023.02 as well.
  • erlinit 1.12.3
