[gatsby-transformer-documentationjs] Add Support for More jsdoc Fields?

[phil-lgr]

I was reading the code source of https://github.com/gatsbyjs/gatsby/tree/master/packages/gatsby-transformer-documentationjs#readme

and I was wondering if we could add support for more JSDOC fields

currently, I can see problems with:

• @default -> I get always null
• @todo -> not sourced (always just ids with no values)

A few links:

• https://github.com/documentationjs/documentation
• Page using gatsby-transformer-documentationjs: https://www.gatsbyjs.com/docs/reference/config-files/gatsby-node/#apis
• Source of above page: https://github.com/gatsbyjs/gatsby/blob/master/packages/gatsby/src/utils/api-node-docs.ts

Usage example:
