build started to break wtih an error `No such file or directory @ rb_sysopen - /home/build/.ssh/gem-private_key.pem`

Hello fellows 👋 We were building the version_gem in Wolfi OS but the build started to fail when we bump the version from 1.1.0 to 1.1.4, then I noticed that there is a signing_key added to the process of releasing the software here I'm assuming the build is failing due to that because it looks for a private key to sign the software, so, is it possible to release the software without signing?

Thanks.
