As an accessibility improvement, specify the navigation landmark for the element of our docs that contains the table of contents generated for the specific API page.

Here's how the node docs work.
1:1 relationship from lib/<module>.js to doc/api/<module>.md.
Each type of heading has a description block.
# module
<!--introduced_in=v0.10.0-->
> Stability: 2 - Stable
A description and examples.
## module.property
<!-- YAML
added: v0.10.0
-->
* {type}
A description of the property.
## module.someFunction(x, y, [z=100])
<!-- YAML
added: v0.10.0
-->
* `x` {string} The description of the string.
* `y` {boolean} Should I stay or should I go?
* `z` {number} How many zebras to bring. **Default:** `100`.
A description of the function.
## module.someNewFunction(x)
<!-- YAML
added: REPLACEME
-->
* `x` {string} The description of the string.
This feature is not in a release yet.
## Event: 'blerg'
<!-- YAML
added: v0.10.0
-->
* `anArg` {type} A description of the listener argument.
Modules don't usually raise events on themselves. `cluster` is the
only exception.
## Class: SomeClass
<!-- YAML
added: v0.10.0
-->
A description of the class.
### SomeClass.classMethod(anArg)
<!-- YAML
added: v0.10.0
-->
* `anArg` {Object} Just an argument.
* `field` {string} `anArg` can have this field.
* `field2` {boolean} Another field. **Default:** `false`.
* Returns: {boolean} `true` if it worked.
A description of the method for humans.
### SomeClass.nextSibling()
<!-- YAML
added: v0.10.0
-->
* Returns: {SomeClass | null} The next `SomeClass` in line.
`SomeClass` must be registered in `tools/doc/type-parser.mjs`
to be properly parsed in `{type}` fields.
### SomeClass.someProperty
<!-- YAML
added: v0.10.0
-->
* {string}
The indication of what `someProperty` is.
### Event: 'grelb'
<!-- YAML
added: v0.10.0
-->
* `isBlerg` {boolean}
This event is emitted on instances of `SomeClass`, not on the module itself.
- Classes have (description, Properties, Methods, Events).
- Events have (list of listener arguments, description).
- Functions have (list of arguments, returned value if defined, description).
- Methods have (list of arguments, returned value if defined, description).
- Modules have (description, Properties, Functions, Classes, Examples).
- Properties have (type, description).
