docs: Check that the terminal supports the provided theme, and applies
          the theme to the terminal if possible.
  
          If the terminal doesn't support the theme, this falls back to the
          default theme. The default theme only requires 8 colors so it
          should be compatible with any terminal that supports basic colors.
