The corpora is required for the install or newspaper3k or else it errors.
I tried pip installing, cloning & downloading older versions of newspaper3k before realising.
While the change seems minor it may prevent users from being deterred because they couldn't get the library working.
As per [their blog post of the 27th April](https://blog.readthedocs.com/securing-subdomains/) ‘Securing subdomains’:
> Starting today, Read the Docs will start hosting projects from subdomains on the domain readthedocs.io, instead of on readthedocs.org. This change addresses some security concerns around site cookies while hosting user generated data on the same domain as our dashboard.
Test Plan: Manually visited all the links I’ve modified.
Without `sudo apt-get install python3-pip` as an additional step, `pip3` command would not be available.
```
$ pip3 install newspaper3k
The program 'pip3' is currently not installed. You can install it by typing:
sudo apt-get install python3-pip
```
