Notebook url is unformatted

I am running Jupyter Notebooks inside docker and I get the following output:
```
To access the notebook, open this file in a browser:
file:///root/.local/share/jupyter/runtime/nbserver-1-open.html
Or copy and paste one of these URLs:
http://(7044e6686b03 or 127.0.0.1):8888/?token=25c62b211cef62f14ce041dea3d22d5d7d09e60bd367fef2
```
I thought I would fix it but it turns out this has been already fixed some 8 months ago yet it does not reflect in the notebook I am using. The desired format is something like this:
```
Or copy and paste one of these URLs:
http://7044e6686b03:8888/?token=25c62b211cef62f14ce041dea3d22d5d7d09e60bd367fef2
or,
http://127.0.0.1:8888/?token=25c62b211cef62f14ce041dea3d22d5d7d09e60bd367fef2
```

The version of packages I am using are:
```
jupyter==1.0.0
jupyter-client==5.2.4
jupyter-console==6.0.0
jupyter-core==4.4.0
notebook==5.7.8
```

Reproduce the notebook server startup output using the listed package versions, then trace where the access URLs are formatted. Compare the installed behavior with the requested hostname:port form and verify that the output no longer includes parentheses around the hostname.
