* Add `#main-content` to some pug pages
This fixes our `skip-to-content` accessibility anchor links. Alternatively or additionally, we can set `suppressSkipToContent = true` in some pages: that will remove the anchor link in the page.
While working on this, I noticed that sometimes we still have a bit of extra nesting or components that should maybe be out of `<main>` or `#main-content`. In a future PR we can maybe update these elements to target the "real core content" of the page.
* Add `suppressSkipToContent` in confirm-email page
