Split queries and mutations big table

Hi,
Today graphql-markdown is producing a single big (HTML) table listing all the possible Queries together.
A similar table is created for all available Mutations.
This means that in the TOC you have only 2 links "Queries" and "Mutations" and you cannot jump straight to a particular query or mutation... you need to scroll these tables.

In case the GraphQL schema gets large, these tables become cumbersome to navigate.
Would that be possible to produce markdown that results in each Query and each Mutation having its own Markdown subsection (just like it happens for "Objects", "Enums", etc etc) ?

I might try to submit a PR if that would be welcome
