Deprecate cli theme options

[mimarz]

As a result of new and expanding features in Designsystemet, we are deprecating cli options related to tokens creation.

Our config file will be the main source for configuring Designsystmet.

Deprecated options:

  -m, --main-colors <name:hex...>     Main colors
  -s, --support-colors <name:hex...>  Support colors
  -n, --neutral-color <hex>           Neutral hex color
  -f, --font-family <string>          Font family (experimental) (default: "Inter")
  -b, --border-radius <number>        Unitless base border-radius in px (default: 4)
  --theme <string>                    Theme name (ignored when using JSON config file) (default:"theme")
