Includes period(.) when autolinking

Hello, if the url is at the end of a sentence, the auto-linking incorrectly includes the period(.) as part of the url which means the url fails.

For example:

```
My first paragraph. This is my website url https://google.com.

This is another paragraph.
```

In the example above the autolinking results in incorrectly hyperlinking ```https://google.com.```
