Other variations of syntax highlighting to explore for accessible-pygments

[trallard]

From #38

• high contrast themes
• Verify the "accessible themes" suggested by VSCode, namely:
  • GitHub: Accessible to most forms of colourblindness and matches the themes in GitHub's settings.
  • Gotthard: Optimized for approximately 20 programming languages. Blinds. Created with Deuteranopia in mind and possesses a high contrast colour ratio.
  • Greative. Considers both colourblindness and light sensitivity.

Some of these styles are also optimised for colourblindness and light sensitivity, so it is worth considering. And ofc because I am biased, and I made sure that the colours in pitaya-smoothie are WCAG compliant and colourblind friendly too, I'd also like to propose adding this to the package
