Respect output format option

[vadyvas]

Is your feature request related to a problem? Please describe.

respect logs in CI can be very large and noisy, which increases storage usage and makes results harder to read.

Current formats:

• lint: stylish, codeframe, json, checkstyle, codeclimate, summary, markdown, github-actions
• scorecard-classic: stylish, json
• stats: stylish, json, markdown

Describe the solution you'd like

1. Add formats to respect commands (e.g. codeclimate, github-actions, summary...)

2. Add additional CI-friendly format:

• junit (JUnit XML) for CI test reports (GitLab / Bitbucket)
  https://docs.gitlab.com/ci/testing/unit_test_reports/#junit-xml-format-specification
  https://support.atlassian.com/bitbucket-cloud/docs/test-reporting-in-pipelines/

3. Optional: if --format is not provided, detect CI and pick a better default format.

Describe alternatives you've considered
