There's a merged pull request on the void-packages repository

python3-dulwich: update to 0.20.44.
https://github.com/void-linux/void-packages/pull/37870

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

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

`xbps-query -RX python3-dulwich` gives `hg-git-0.9.0_3` and `radicale-3.1.7_1`. I tested the first one with the [update PR](https://github.com/void-linux/void-packages/pull/37865). The second one doesn't seem to [require](https://github.com/Kozea/Radicale/blob/v3.1.7/setup.py#L52) it anymore.
