Fix bool enums (#1080)

* add (failing) test case for boolean enum and const values

failing with:

```
[
  {
    code: 1,
    data: {
      schemaUri: [ 'file:///default_schema_id.yaml' ],
      values: [ true, false ]
    },
    message: 'Value is not accepted. Valid values: true, false.',
    range: {
      end: { character: 15, line: 0 },
      start: { character: 11, line: 0 }
    },
    severity: 1,
    source: 'yaml-schema: file:///default_schema_id.yaml'
  }
]
```

* fix the issue for `boolean` values in `enum`

this is the same fix for `enum` that has been applied a while back for `const` values here: e6165e4

fixes issue: #1078
