summary - suppress spinner if noColor is true

[jzweifel]

This behavior is consistent with how html-report behaves, and is desireable for CI environments such as GitHub Actions where the spinner output won't look near as pretty.

I'm attempting to embed openapi-changes into a GitHub workflow, so that I can have it error a check on a PR if a PR were to introduce any breaking changes. I'm using the summary markdown output feature, in an action a little like this:

name: 'Check for Breaking OAS Changes'
description: 'Compares the version of a spec against what is currently in main.'
inputs:
  spec-to-scan: # local path to a spec to check for changes
    description: 'Repository-local path to a spec to check for breaking changes.'
    required: true
runs:
  using: 'composite'
  steps:
    # Check out the repository
    - uses: actions/checkout@v3

    - name: Install pb33f/openapi-changes
      uses: ./.github/actions/install-pb33f-openapi-breaking-changes

    - name: Get all changed oas files
      id: changed-oas-files
      uses: tj-actions/changed-files@v44
      with:
        # Avoid using single or double quotes for multiline patterns
        files: |
            services/**.{yml,yaml}

   name: 'Check for Breaking OAS Changes'
description: 'Compares the version of a spec against what is currently in main.'
inputs:
  spec-to-scan: # local path to a spec to check for changes
    description: 'Repository-local path to a spec to check for breaking changes.'
    required: true
runs:
  using: 'composite'
  steps:
    # Check out the repository
    - uses: actions/checkout@v3

    - name: Install pb33f/openapi-changes
      uses: ./.github/actions/install-pb33f-openapi-breaking-changes

    - name: Get all changed oas files
      id: changed-oas-files
      uses: tj-actions/changed-files@v44
      with:
        # Avoid using single or double quotes for multiline patterns
        files: |
            services/**.{yml,yaml}

    - name: Diff all changed oas files
      shell: bash
      if: steps.changed-oas-files.outputs.any_changed == 'true'
      env:
        ALL_CHANGED_FILES: ${{ steps.changed-oas-files.outputs.all_changed_files }}
      run: |
        set +e
        MARKDOWN_OUTPUT="# Summary of changes"
        SHOULD_FAIL=false
        for file in ${ALL_CHANGED_FILES}; do
          MARKDOWN_OUTPUT+="\n\n"
          MARKDOWN_OUTPUT+="## $file"
          MARKDOWN_OUTPUT+=$(openapi-changes summary --no-logo --no-color --markdown ./ "$file")
          CHANGES_EXIT_CODE=$?
          if [ $CHANGES_EXIT_CODE -ne 0 ]; then SHOULD_FAIL=true; fi;
        done
        EOF=$(dd if=/dev/urandom bs=15 count=1 status=none | base64)
        echo "breaking_changes_markdown<<$EOF" >> $GITHUB_OUTPUT
        echo -e "$MARKDOWN_OUTPUT" >> $GITHUB_OUTPUT
        echo "$EOF" >> $GITHUB_OUTPUT
        echo "breaking_changes_detected=$SHOULD_FAIL" >> $GITHUB_OUTPUT
        set -e

I noticed that the output from summary, even with --no-logo --no-color --markdown would include many lines from the spinner, and ultimately caused a few rendering issues within the markdown as well.
