links to stable source tar.gz broken

[Brian Martin]

On https://forge.rust-lang.org/other-installation-methods.html the link to the stable source and its signature are both missing the version number and lead to a 404.

Currently the HTML contains:

<div class="source-table">
  <div>
      <span>Stable</span>
      <a href="https://static.rust-lang.org/dist/rustc--src.tar.gz">.tar.gz</a>
      <a href="https://static.rust-lang.org/dist/rustc--src.tar.gz.asc">.asc</a>
  </div>
  <div>
      <span>Beta</span>
      <a href="https://static.rust-lang.org/dist/rustc-beta-src.tar.gz">.tar.gz</a>
      <a href="https://static.rust-lang.org/dist/rustc-beta-src.gz.asc">.asc</a>
  </div>
  <div>
      <span>Nightly</span>
      <a href="https://static.rust-lang.org/dist/rustc-nightly-src.tar.gz">.tar.gz</a>
      <a href="https://static.rust-lang.org/dist/rustc-nightly-src.tar.gz.asc">.asc</a>
  </div>
</div>

Expected behavior is that the stable rustc source url would contain the latest stable version number eg: https://static.rust-lang.org/dist/rustc-1.34.1-src.tar.gz which does appear to be a valid url for the stable source.

Sorry about that! Fixed.
