Description

add warning message for applyHtmlTransforms.

there will be an abnormal scene, when we try to use some tags in head element, such as div.

here is an example:

<!DOCTYPE html>
<html>
  <head>
    <div>test div in head</div>
    <meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
  </head>

  <body>
    body
  </body>
</html>

it will be better for developer, if vite provide some warn message.

I guess this warning won't happen that much, but I think the complexity is small enough.

Note for other reviewers: I confirmed that custom elements are not allowed in <head>.
