Local asset building

• Set nodejs_version: "20" inside .ddev/config.yaml (for vite)
• Fix missing Font Awesome variables (possibly connected with this 3ae27f9)

    ╷
155 │     attention $admonition-border-color-highlighted #{$fa-var-bell},
    │                                                      ^^^^^^^^^^^^
    ╵
  assets/sass/_variables.scss 155:54  @import
  assets/sass/theme.scss 9:9          root stylesheet
`

edit: I can confirm it's connected with the linked change: with Font Awesome 6.7.2 the variables where there.

@linawolf let's close this one for now? Or do we want to fix the started Font Awesome 7 integration ?
