refactor(web): common template for index pages of tvl and atward r/2585
Use simple string interpolation based approach to templating and allow
changing the main body, the title and to inject extra HTML into the head
element. Additionally we can use `https://tvl.fyi/` instead of `/` when
referring to assets.

One limitation currently is that the template only works for index pages
(it link to self using `href="/"`), but this should be easy to fix.

For atward, instead of using the `onload` attribute of `body`, we now
register an event listener in JavaScript which makes the template code
less complicated. When building the derivation the template is rendered
to HTML and injected into the source.
