Replace trending repositories name selector
Replace trending repositories name selector

I was trying to use this library, but unfortunately it does not work.  I think it because of parsing problem

currently https://github.com/trending - page does not have `repo-list-item .repo-list-name a`  (at least I cant inspect it) .

So I have changed locally  with `.repo-list h3 a` and it's worked in bottom case

```
var Trending = require("github-trend");
var scraper = new Trending.Scraper();

scraper.scrapeTrendingRepos("").then(function (repos) {
        repos.forEach(function (repo) {
            console.log(repo.owner);
            console.log(repo.name);
        });
        res.send('Got repos ' + JSON.stringify(repos));
    }).catch(function (err) {
        console.log(err.message);
    });
```
