Drop support for Python < 3.8

[afuetterer]

I suggest giving this project the same treatment as Bertopic:

• drop Python 3.6-3.7
• add support for 3.8-3.12

See MaartenGr/BERTopic#1942

[MaartenGr]

@afuetterer Thanks, totally agree! Aside from security/support reasons, the number of users using Python < 3.8 is also low.

Already opened #230.

Migration to pyproject.toml as well?

[MaartenGr]

@afuetterer Yeah, that would be great. But again, only if you have the time, don't want to ask too much of you 😉

[afuetterer]

Sure thing.

Actually even if you don't want to use hatch/hatchling as the build backend. You can use hatch to migrate from setup.py to pyproject.toml pretty easily.

git clone https://github.com/MaartenGr/KeyBERT.git
cd KeyBERT
hatch new --init

Some tweaks here and there, but the basic skeleton is alright. For example it wants to sort keywords alphabetically.

Done via #230.
