CITE and master demos are 404

[tomkralidis]

As reported on GeoQoS, the following services are 404:

• https://demo.pygeoapi.io/cite
• https://demo.pygeoapi.io/master
• https://demo.pygeoapi.io/covid-19

(Note that https://demo.pygeoapi.io/stable works as expected)

Indeed these were auto-deployed as a new version of the geopython/pygeoapi:latest became available about the time of the 404s.
There is now a constant restart of the above containers (who share the same image).
But the error looks more internal, a version mismatch due to some upgrade, so looks like an issue for pygeoapi itself:

Quick analysis: the version mismatch is probably caused by a mix of installments for gunicorn and gevents in the pygeoapi Dockerfile. A mix of a Ubuntu/Debian package gevent 24.2.1 and a pypi install gunicorn 24.1.1. The latter was updated 4 days ago, just inbetween two pygeoapi build/deploys....

Thanks for the analysis @justb4. pygeoapi PR in geopython/pygeoapi#2222 should fix (and thanks for opening the issue in geopython/pygeoapi#2221).
