docs(bike-shed-migration): let markdown deal with extenal links

It is problematic to use {@link} tags with external links because the
markdown parser converts them to links for us before we parse the @links.
This means that the following tag:

```
{@link http://www.google.com Google}
```

get converted to:

```
{@link <a href="http://www.google.com/"></a> Google}
```

Our {@link} parser then converts this to:

```
<a href="<a">&lt;</a>href="http://www.google.com/"></a> Google}
```

which is clearly a mess.  The best solution is not to use {@link} tags
for external links and just use the standard markdown syntax:

```
[Google](http://www.google.com)
```

In the long run, we could look into configuring or modifying `marked` not
to convert these external links or we could provide a "pre-parser"
processor that dealt with such links before `marked` gets its hands on it.
