v1.3.1

• Files are checked in parallel. This made actionlint around 1.3x faster with 3 workflow files in my environment
• Manual for man command was added. actionlint.1 is included in released archives. If you installed actionlint via Homebrew, the manual is also installed automatically
• -version now reports how the binary was built (Go version, arch, os, ...)
• Added Command struct to manage entire command lifecycle
• Order of checked files is now stable. When all the workflows in the current repository are checked, the order is sorted by file names
• Added fuzz target for rule checkers
