docs: Fix double border in the footer

What's broken?

The documentation is wrong or misleading

Where in the spec or docs?

The footer on every docs page.

https://modelcontextprotocol.io/docs

What should happen?

The footer is showing two borders above the copyright text:

I have a fork which fixes it to look like:

Solution

Fork: https://github.com/modelcontextprotocol/modelcontextprotocol/compare/main...TobCar:modelcontextprotocol:main?expand=1

Basically delete footer.js and add this to style.css:

#footer > div:first-of-type::after {
  content:
    "Copyright © Model Context Protocol a Series of LF Projects, LLC.\A "
    "For web site terms of use, trademark policy and other project policies please see https://lfprojects.org.";

  /* Fill the row beside the icons; the spacing comes from the row's own gap */
  flex: 1;

  white-space: pre-line;
  text-align: center;
  font-size: 0.875rem;
  line-height: 1.5;
  color: rgb(var(--gray-500));
}

This is the same approach we use on https://getlemma.com/docs to add text to our footer.

I tried to open a pull request but recent changes made PRs collaborator-only. (Understandable honestly!)
