docs(linter): Add configuration option docs for eslint/sort-keys rule. (#15014)

Part of #14743.

Generated docs:

```md
## Configuration

This rule accepts a configuration object with the following properties:

### allowLineSeparatedGroups

type: `boolean`

default: `false`

When true, groups of properties separated by a blank line are sorted independently.


### caseSensitive

type: `boolean`

default: `true`

Whether the sort comparison is case-sensitive (A < a when true).


### minKeys

type: `integer`

default: `2`

Minimum number of properties required in an object before sorting is enforced.


### natural

type: `boolean`

default: `false`

Use natural sort order so that, for example, "a2" comes before "a10".


### sortOrder

type: `"desc" | "asc"`

default: `"asc"`

Sorting order for keys. Accepts "asc" for ascending or "desc" for descending.
```
