perf: replace ignoreDOMNode with ignoreDomNode

The new TRE engine uses a custom parser to support this callback.
Therefore, a supplementary tree traversal after parsing is not required
anymore, removing a O(n) computational cost.

BREAKING CHANGE: `ignoreDOMNode` is now `ignoreDomNode` for naming
consistency.
