New review comment by meator on void-packages repository

https://github.com/void-linux/void-packages/pull/38207#discussion_r928219160

Comment:
`tags` is seldomly used in Voidlinux packages and its usefulness is questionable. `xbps-query` can't search packages by tags, so it only appears in the package metadata and it isn't directly used by XBPS nor any utility that I would know of.

```sh
. /usr/share/xbps.d/00-repository-main.conf && wget -qO - "$repository/x86_64-repodata" | tar --zstd -xOf - index.plist | fgrep -B 40 "<key>tags"
```
This shell command searches for everything in the repository index that contains the `tags` property. This shows that the only package in the main repository with the `x86_64` architecture is `tuigreet`. This shows that only a single package in the entire Voidlinux repository is using `tags`.
