Hatch a pet from an egg and a hatching potion.

Habitica API: https://cotlet.dev/docs/api/habitica.md

`POST https://cotlet.dev/api/v1/habitica/pet/hatch`

Access: write. Confirm: waits for the user's OK before it runs.

Uses one egg and one potion and returns the new pet. A potion that does not fit the egg changes nothing and the call returns an error. It uses up the items, so check the pair first.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `egg` | string | yes | Egg name from list_pets_and_mounts, for example Wolf. |
| `hatching_potion` | string | yes | Potion name from list_pets_and_mounts, for example Base. |
