George Kalpakas 0add00a743 build(docs-infra): throw error if using title on code snippets (#26514)
Since #26396, the `title` property is ignored and `header` should be
used instead for specifying a code snippet's header.

This commit ensures that we don't accidentally set `title` have it be
silently ignored.
