Documentation website improves

• on website deploy, instead of reading size-limit config to get a size it's better to use bundlephobia api because ppl will use this service to check the size Fixed in Load bundle size from bundlephobia instead of size-limit file #1009
• when a screen is small enough we hide a text from the logo, but it seems that in some cases we could display it for a bit longer
  
• when a screen is small the header might look strange sometimes:
  
• Add an ability to have theme-based chart colors #1001
• migrate to postcss from css
• introduce stylelint
• try to use client-side js-based adaptive logo rather than have 4 icons and load them as images
• tbc
