SSR docs

[nichoth]

current docs are here: https://tonicframework.dev/#ssr

It would be good to make an example of SSR. The site says to look at the docs website. I see there is a prerender function call.

However, when I make an example using prerender, it throws an error

demonstration main % node ./ssr/greeting.js 
/Users/nick/code/demonstration/node_modules/tonic-ssr/node_modules/@socketsupply/tonic/index.js:47
      const html = this.outerHTML.replace(this.innerHTML, '...')
                                  ^

TypeError: Cannot read properties of undefined (reading 'replace')

The docs website I think is a little too complex for example purposes.
