Based on https://github.com/payloadcms/payload/pull/13060 which should
be merged first
This PR adds ability to update number fields atomically, which could be
important with parallel writes. For now we support this only via
`payload.db.updateOne`.
For example:
```js
// increment by 10
const res = await payload.db.updateOne({
data: {
number: {
$inc: 10,
},
},
collection: 'posts',
where: { id: { equals: post.id } },
})
// decrement by 3
const res2 = await payload.db.updateOne({
data: {
number: {
$inc: -3,
},
},
collection: 'posts',
where: { id: { equals: post.id } },
})
```
