Add Script to Create Zip Archive for Distribution

[tajmone]

⚠️ IMPORTANT — This must be implemented after Issue #72 is fixed.

• Add a script to create a Zip archive of the current Hugo Book for quick distribution and inclusion with tagged releases:
  • Add to the Zip archive the following files:
    • The HTML version (copy it).
    • The required image assets (copy them inside images/ subfolder).
    • A README.txt with a brief presentation (needs to be created).
    • The LICENSE file (copy it).
    • An ad hoc standalone AsciiDoc version (generate it) which exploits attributes and preprocessor directives to ensure:
      • :toc: is set to left.
      • :imagesdir: points to the custom images/ subfolder.
      • any other required settings are correctly in place.
  • Name the Zip file hugo-book-vX.Y.Z-html-asciidoc.zip, where vX.Y.Z should be the current version number.
    • Find a way to make the script aware of the current version of the book.
    • Exclude the created Zip archive and any temporary copied/created files from Git tracking.
  • Check if the AsciiDoc source is able to find the included images, and/or provide a sample build command with the required options to make it work.
• Document it:
  • Main README.md folder contents and project description.
  • Main README.md Changelog.

When I submitted the first release of the new Hugo Book port to the IF Archive I provided them with a Zip archive (hugo-book-v1.0.0-html-asciidoc.zip) containing the HTML book and the standalone AsciiDoc source:

• https://ifarchive.org/indexes/if-archive/programming/hugo/manuals/

This is the same Zip archive which I've added as an attachment to the project release:

• https://github.com/tajmone/hugo-book/releases/tag/1.0.0

But I forgot to include the required images for the AsciiDoc version (not a huge deal, since the HTML doc embeds all the images, so they can be easily extract from it by dragging them to a folder).

So I decided that with the next release I would add to the repository a shell script to automate the creation of these Zip archives for quick distribution. Although it's not mandatory that I add this script with the upcoming version, it would be a good time to do so.
