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

khal: update to 0.10.5.
https://github.com/void-linux/void-packages/pull/38583

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)
- I built this PR locally for these architectures (if supported. mark crossbuilds):
  - aarch64-musl (crossbuild)

Since version 0.10.5 there is no longer a `__khal` file. This is why I deleted line 26.
