Subject: [PATCH] docs: module-signing: adjust guide after sha1 and sha224 support is gone

Commit 16ab7cb5825f ("crypto: pkcs7 - remove sha1 support") and commit
fc3225fd6f1e ("module: Do not offer sha224 for built-in module signing")
removes sha1 and sha224 support for kernel module signing.

Adjust the module-signing admin guide documentation to those changes.
