Object details in type description is not escaped

[arantes555]

Introduced in #286 (comment)

typedoc-plugin-markdown now puts object details in type description tables. The problem is with objects of the form :

{ [id: string]: "ok" | "ko"; }

The [id: string] part is interpreted as a link by some markdown parsers (examples : WebStorm, and check-md : https://github.com/whxaxes/check-md).

Solution: wrap it in backquotes:

{ [id: string]: "ok" | "ko"; }

(plus, it seems more coherent to me, as most other types and variable names are in backquotes)
