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.

By setting `renderExamples.ignoreBrokenExamples = true` the doc-gen will
not fail if there is something wrong with an example. Instead it will
just log a warning.
