I am using github/cache action to achieve this (I have not had time to thoroughly asses the impact).

- uses: actions/cache@0c45773b623bea8c8e75f6c82b208c3cf94ea4f9 # v4.0.2
   with:
      save-always: true
      path: ~/.local/share/aquaproj-aqua
      key: test-modules-v1-aqua-installer-${{runner.os}}-${{runner.arch}}-${{hashFiles('**/aqua/**/*.yaml')}} # Change key
      restore-keys: |
          test-modules-v1-aqua-installer-${{runner.os}}-${{runner.arch}}-

and
