Remove 40 dead CODEOWNERS rules

[DanielSwift1992]

Description

Resolves 40 stale references in CODEOWNERS. The lines themselves were left unchanged while the paths they referenced disappeared from the tree.

# a stale line
sed -n '46p' .github/CODEOWNERS

# tracked files under the referenced paths
git ls-files -- 'website/' 'builtin/logical/cassandra/' | wc -l
