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

set update to ignore alpha/beta/dev/rc versions
https://github.com/void-linux/void-packages/pull/33327

Description:
I looked at all the updates which correspond to alpha/beta/dev/rc versions as follows:
```
$ wget -c http://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt
$ cat void-updates.txt | grep -- '-> [0-9.-]*[^0-9. -]' | awk '{print $1}' | sort -u | xargs -n1 ./xbps-src update-check > todo.txt
$ wc -l todo.txt
362 todo.txt
```
After the patch, the same thing gives 195 updates, can diff before/after to see the change. There are a few packages which I didn't look into (e.g. debian version suffixes).

Most is `*a[0-9] *b[0-9] *rc[0-9] *.dev[0-9]`, especially for python packages, I wonder if that should be default, but then some packages use versions that match some of those.

No file other than `srcpckgs/*/update` is touched by this commit.
