abnf dependency generates warnings on modern node versions

[duncanbeevers]

Installing dependencies from https://github.com/oai/OpenAPI-Specification generates a warning about an unsupported node engine.

$ npm install
npm warn EBADENGINE Unsupported engine {
npm warn EBADENGINE   package: '[email protected]',
npm warn EBADENGINE   required: { node: '~0.10.10' },
npm warn EBADENGINE   current: { node: 'v22.13.0', npm: '10.9.2' }
npm warn EBADENGINE }

The warning comes from that project's dependency on mdv, and mdv's dependency on this old version of the abnf package.

I haven't investigated the upgrade path from abnf 0.0.5 to its current version 4.3.1, but thought it was at least worth discussing.
