Alessio Gravili 9f9db3ff81 chore: bump prettier, re-enable prettier for docs (#11695)
## Introducing Prettier for docs

Prettier [was originally disabled for our docs as it didn't support MDX
2.0](1fa636417f),
outputting invalid MDX syntax.

This has since been fixed - prettier now supports MDX 2.0.

## Reducing print width

This also reduces the print width for the docs folder from 100 to 70.
Our docs code field are very narrow - this should help make code more
readable.

To add a Checkbox Field, set the `type` to `checkbox` in your [Field Config](./overview):
```ts
import type { Field } from 'payload'
export const MyCheckboxField: Field = {
// ...
type: 'checkbox', // highlight-line
}
```
## Config Options
| Option | Description |
| ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **`name`** \* | To be used as the property name when stored and retrieved from the database. [More](/docs/fields/overview#field-names) |
| **`label`** | Text used as a field label in the Admin Panel or an object with keys for each language. |
| **`validate`** | Provide a custom validation function that will be executed on both the Admin Panel and the backend. [More](/docs/fields/overview#validation) |
| **`index`** | Build an [index](/docs/database/overview) for this field to produce faster queries. Set this field to `true` if your users will perform queries on this field's data often. |
| **`saveToJWT`** | If this field is top-level and nested in a config supporting [Authentication](/docs/authentication/overview), include its data in the user JWT. |
| **`hooks`** | Provide Field Hooks to control logic for this field. [More details](../hooks/fields). |
| **`access`** | Provide Field Access Control to denote what users can see and do with this field's data. [More details](../access-control/fields). |
| **`hidden`** | Restrict this field's visibility from all APIs entirely. Will still be saved to the database, but will not appear in any API or the Admin Panel. |
| **`defaultValue`** | Provide data to be used for this field's default value, will default to false if field is also `required`. [More](/docs/fields/overview#default-values) |
| **`localized`** | Enable localization for this field. Requires [localization to be enabled](/docs/configuration/localization) in the Base config. |
| **`required`** | Require this field to have a value. |
| **`admin`** | Admin-specific configuration. [More details](./overview#admin-options). |
| **`custom`** | Extension point for adding custom data (e.g. for plugins) |
| **`typescriptSchema`** | Override field type generation with providing a JSON schema |
| **`virtual`** | Provide `true` to disable field in the database. See [Virtual Fields](https://payloadcms.com/blog/learn-how-virtual-fields-can-help-solve-common-cms-challenges) |
_\* An asterisk denotes that a property is required._
## Example
Here is an example of a Checkbox Field in a Collection:
```ts
import type { CollectionConfig } from 'payload'
export const ExampleCollection: CollectionConfig = {
slug: 'example-collection',
fields: [
{
name: 'enableCoolStuff', // required
type: 'checkbox', // required
label: 'Click me to see fanciness',
defaultValue: false,
},
],
}
```
