v0.23.0

Release notes

Added

• east.yml now supports specifying samples in nested subdirectories. For example, if there is a
  sample located under samples/basic/blinky, it can be specified in east.yml simply as
  - name: basic/blinky. Samples build artefacts will be stored in the build directory under
  the same subdirectory structure. This feature allows users to organize their samples in a more
  structured way, instead of having all samples in the root samples directory.
  This feature is documented in the docs/configuration.md file under Samples section.
  Suggested by @Finwood in #111.

Fixed

• east release command, which failed to find project dir, when run with
  EAST_DONT_USE_TOOLCHAIN_MANAGER=1 option.
• east codechecker check, which previous failed to find compile_command.json file on
  builds that were using sysbuild.
