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

aerc: update to 0.6.0.
https://github.com/void-linux/void-packages/pull/34316

Description:
The original upstream maintainer, Drew Devault, has stepped down and a
fork was created (with Drew's approval) under the same name. The fork
has patched in a large backlog of crashes and bug fixes and put out a
new version 0.6.0 recently. I think now that the aerc community has
consolidated on this fork it would be appropriate to update our package
to the new upstream.

More info about the fork and new maintainer can be found in this
discussion: https://lists.sr.ht/~sircmpwn/aerc/%3CCFBVJ3G1Y4YB.ZI6C02D0MS0S%40diabtop%3E
