Removing a recipient does not remove their public key from .public-keys

[dAnjou]

Summary

When people leave the project we'd like to remove them from the gopass store completely.

Steps To Reproduce

gopass recipients remove KEY_ID

Expected behavior

The person's key and all their other data is removed from the store.

Actual behavior

The person is removed as a recipient from .gpg-id but their key stays in .public-keys. What's the reason and motivation behind this? We'd like to clean this up, can we simply remove the key files without compromising the integrity of the store?

Environment

• OS: macOS 12.4
• gopass Version: 1.14.4 go1.18.5 darwin arm64
• Installation method: brew

This sounds like a bug.
We should clean up after removing a recipient.
