unable to inject shell to composite action

Describe the bug Unable to pass the shell via input parameter to the composite action.

To Reproduce Steps to reproduce the behavior:

1. create following composite action:

name: 'test actions'
description: 'test action description'
inputs:
  shell:
    description: 'shell to use'
    required: false
    default: bash
runs:
  using: "composite"
  steps:
    - name:
      run: echo "bla bla bla"
      shell: ${{ inputs.shell}}

1. use the action in some workflow
2. Job fails on the ‘Set up job’ phase, printing the following errors:

Current runner version: '2.274.2'

Error: Fail to load myci-actions\add-pacman-repo\master\action.yml

where (Line: 25, Col: 14) corresponds to the last line of the action from step 1. I.e. shell: ${{ inputs.shell}}

Expected behavior The action works fine and uses the shell passed in as input argument to the action.

FYI, rather than duplicating steps, I ended up sym-linking OS-specific shells to a known location, and changed my steps to specify that new location as shell parameter.

    - name: Create bash-or-msys2
      shell: bash
      run: |
        if [[ "$RUNNER_OS" == "Windows" ]]; then
            powershell New-Item -ItemType SymbolicLink \
              -Path  "D:/a/_temp/setup-msys2/bash-or-msys2.cmd" \
              -Target "D:/a/_temp/setup-msys2/msys2.cmd"
        else
            sudo ln -sf $(which bash) /usr/local/bin/bash-or-msys2
        fi
        ...
    - name: Upgrade ASDF to the Latest Version
      shell: bash-or-msys2 {0}
      run: |
        if [[ "${{ inputs.asdf-version }}" != "latest" ]]; then
            echo ::group::Installing ASDF ${{ inputs.asdf-version }}
            ros install asdf/${{ inputs.asdf-version }}
        else
            echo ::group::Installing latest ASDF
            ros install asdf
        fi
        echo ::endgroup::

Not ideal, but not as ugly as duplicating each and every step.

We are still experiencing this issue using ubuntu-latest runners.
