shell: bash steps continue to use the system perl

[skirmess]

On Windows, if we use shell: bash the PATH env variable always starts with /mingw64/bin and /usr/bin.

  job:
    runs-on: windows-latest
    steps:
      - uses: shogo82148/actions-setup-perl@v1

      # uses powershell and runs with the Perl from actions-setup-perl
      - run: perl -V

      # uses bash and runs with the system Perl
      - run: perl -V
        shell: bash

I can't see a way to change this behavior as the /usr/bin directory seems to be hard coded somehow and I'm not sure if deleting /usr/bin/perl.exe on Windows is a good idea? If you don't see a way to fix the path we should document that the bash shell is not supported under Windows.

Thank you for your report.
I seems that bash on Windows automatically adds /usr/bin into the PATH environment value.

I'm not sure if deleting /usr/bin/perl.exe on Windows is a good idea?

deleting /usr/bin/perl.exe on Windows is a bad idea. Because Git on Windows uses perl.
It may break the actions/checkout action.

Unfortunately, I have no idea...
I'll document this issue.

Would be also nice to add path to the perl containing directory to the action outputs.
