speed.python.org: Tidy up 'About' page

Thanks. I tend to prefer the principle of a single link the first time something is mentioned, then no link in subsequent mentions. We don’t think we need so many references to the upstream codespeed site. Maybe we should reword the page to only refer once to the branch that actually runs the site. And we don't need the whole issues sentence, in the years it has been running no one used that.

I removed:

<p>This site runs on top of <a href="https://www.djangoproject.com/">Django</a>
and <a href="https://github.com/tobami/codespeed">Codespeed</a>.</p>

to avoid the duplicate references. We note Django in the footer anyway.

And we don't need the whole issues sentence, in the years it has been running no one used that.

I suggest keeping it, it doesn’t hurt and may be of help to someone someday.
