- Remove the previous summary file is present to avoid showing stale
contents from old summaries.
- Extract the logic to write summary heading and lines to dedicated
functions in output.sh to make it easier adding new formats in the
future.
- Allow using both Prettier and StandardJS at the same time by removing
JAVASCRIPT_DEFAULT_STYLE and TYPESCRIPT_DEFAULT_STYLE
configuration variables. They create a confusing corner case that
Super-linter already handles with its core logic that's in place to
enable and disable linters.
- Document VALIDATE_JAVASCRIPT_PRETTIER and VALIDATE_TYPESCRIPT_PRETTIER
because they were missing from the README.
- Add missing TYPESCRIPT_PRETTIER tests.
