feat: lock documents while being edited (#7970)

## Description

Adds a new property to `collection` / `global` configs called
`lockDocuments`.

Set to `true` by default - the lock is automatically triggered when a
user begins editing a document within the Admin Panel and remains in
place until the user exits the editing view or the lock expires due to
inactivity.

Set to `false` to disable document locking entirely - i.e.
`lockDocuments: false`

You can pass an object to this property to configure the `duration` in
seconds, which defines how long the document remains locked without user
interaction. If no edits are made within the specified time (default:
300 seconds), the lock expires, allowing other users to edit / update or
delete the document.

```
lockDocuments: {
  duration: 180, // 180 seconds or 3 minutes
}
```
