Subject: [PATCH 1/3] Migrate dependencies to pyproject.toml

Move test and dev dependencies into PEP 735 dependency groups.
Update tox.ini and ci.yml to install via --dependency-group.

requirements.txt retained as a stub until beeware/.github#355
lands; see #236 for context.

Subject: [PATCH 2/3] Fix pip dependency group flag

  --dependency-group is not a valid pip flag; the correct flag
  introduced in pip 25.1 (PEP 735) is --group.
