For dependency @lovell/sharp, a vulnerability was found: GHSA-gp95-ppv5-3jc5

The vulnerability concerned Command Injection in post-installation over build environment. This was fixed in version v0.30.5

Updating Sharp to v0.30.5 should remove the vulnerability, or at least, that's what it says on the tin.
