docs: Show project version. Has sub commands.
  
      For this command to work you must specify where the project version is
      stored. You can do that with version_file conf variable. peltak supports
      multiple ways to store the project version. Right now you can store it in a
      python file using built-in __version__ variable. You can use node.js
      package.json and keep the version there or you can just use a plain text
      file that just holds the raw project version. The appropriate storage is
      guessed based on the file type and name.
  
      Example Configuration::
  
          version_file: 'src/mypackage/__init__.py'
  
      Examples:
  
          \b
          $ peltak version                        # Pretty print current version
          $ peltak version --porcelain            # Print version as raw string
          $ peltak version bump patch             # Bump patch version component
          $ peltak version bump minor             # Bump minor version component
          $ peltak version bump major             # Bump major version component
          $ peltak version bump release           # same as version bump patch
          $ peltak version bump --exact=1.2.1     # Set project version to 1.2.1
