This new major release removes support of legacy pypy2 and pypy3 keywords. Please use more specific and flexible syntax to specify a PyPy version:

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        python-version:
        - 'pypy-2.7' # the latest available version of PyPy that supports Python 2.7
        - 'pypy-3.8' # the latest available version of PyPy that supports Python 3.8
        - 'pypy-3.8-v7.3.8' # Python 3.8 and PyPy 7.3.8
    steps:
    - uses: actions/checkout@v2
    - uses: actions/setup-python@v3
      with:
        python-version: ${{ matrix.python-version }}
