Version 0.24.0: Completely overhaul dice probability calculations

[Samasaur1]

Here's what's new:

• Dice probabilities computation is now up to 1000x faster (in my tests). From the user's perspective, nothing else about this should have changed.
  • Chance objects can now be multiplied together (which, mathematically, represents the chance of both occurring)
• Add some more test cases for Chance
• The release script now links to the docs for the specific version (on the releases page), not just the main website.
• GitHub Actions can now deploy docs through the use of the GitHub token
• Typo fixes

Here's what has to happen:

• [x] Ensure the changelog has everything new that is being added
• [x] Bump version (run updateVersion.sh)
  1. Wait for CI
  2. Merge
  3. Run release.sh
