Update Flask-appbuilder and gevent

[Maleware]

Description

This updates two dependencies:

• flask-appbuilde 4.3.10 -> 4.3.11 CVE-2024-25128
• gevent 22.10.2 -> 24.2.1 CVE-2023-41419

Dependencie greenlet has been removed from 3.1.0 constrains.txt since python have to choose it on it's own.

This has only be done for 3.1.0 since customers could update to the latest version of superset we support and having most critical vulnerabilities fixed.

Testing was done with Superset Getting started and was successful.

I looked at this but don't know enough about Python & build processes etc. to comment on it. I'd appreciate if someone else could take a look.
