fix(website): prop mismatch error with ssr by turning off autoprefixing

[Aslemammad]

fixes prop mismatch error with ssr in #344

In transformIndexHtml, waku will transform and return the result to the browser! In this process, vite will apply its transformation which postcss/autoprefixer is part of. Autoprefixer will add the -moz- pseudo-class.
A better solution will be an upstream one, in the bright package which should use autoprefixer control comments and disable the prefixing to the inline CSS part that React will process.

With this PR's solution, what we do is just disable the prefixing for the whole website.

React stream: 
<style>
[data-bright-theme] ::selection { background-color: var(--selection-background) }
  </style>

after transformIndexHtml:
<style>
  [data-bright-theme] ::-moz-selection { background-color: var(--selection-background) }
[data-bright-theme] ::selection { background-color: var(--selection-background) }

  </style>
