Typo in reference title

[demurgos]

There's a small typo in the "Informative References" section:

https://github.com/bmeck/I-D/blob/323af03b5e6f978ff92d41799dd9e4fd0760df1d/javascript-mjs/draft-ietf-dispatch-javascript-mjs-02.txt#L1085

The title of the issue has an extra 5 at the end:

• "Add `application/javascript+module` mime to remove ambiguity5" (current)
• "Add `application/javascript+module` mime to remove ambiguity" (fixed)

(Also, the new line in the URL breaks the link in the HTML-rendered version)
