https://github.com/void-linux/void-packages/pull/49332

Description:
#### 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

#### Notes
- New database schema, users will have to re-initialize their database, see `MU INIT(1)`.
- The README of the mu still states: "Distributions and non-adventurous users are instead recommended to use the [1.10 Release Branch](https://github.com/djcb/mu/tree/release/1.10) or to pick up one of the [1.10 Releases](https://github.com/djcb/mu/releases). ]" [[1]]. However, 1.12.2 is marked as stable.
