python3-chardet: fix split with python2 pkg, revbump
The current template is broken, and won't build a working package. Currently all works, just because there wasn't a revbump since the split.

#### Testing the changes
- I tested the changes in this PR: **YES**

#### Local build testing
- I built this PR locally for my native architecture, **x86_64-glibc**

I tested an update from the previous rev to this, there were no problems with the alternatives.
Also, as the python2 pkg still exists in the repos, I made them `conflict` to ensure there won't be any strange behaviour with alts. 

A patch file from https://github.com/void-linux/void-packages/pull/37061.patch is attached

Subject: [PATCH] python3-chardet: fix split with python2 pkg, revbump

Fix depends.
Drop alternatives (wrong and also obsolete).

Add conflict with the python2 version of the pkgs (as it still exist
in the official bin repos) to ensure that there won't be any issues.
