Inset ring color classes have incorrect names in API table

[dcastil]

On the page https://tailwindcss.com/docs/box-shadow the API table shows following classes:

…

shadow-black | --tw-shadow-color var(--color-black); /* #000 */
shadow-white | --tw-shadow-color var(--color-white); /* #fff */
…

inset-shadow-black | --tw-inset-shadow-color var(--color-black); /* #000 */
inset-shadow-white | --tw-inset-shadow-color var(--color-white); /* #fff */
…

ring-black | --tw-ring-color: var(--color-black); /* #000 */
ring-white | --tw-ring-color: var(--color-white); /* #fff */
…

ring-black | --tw-inset-ring-color: var(--color-black); /* #000 */
ring-white | --tw-inset-ring-color: var(--color-white); /* #fff */
…

The last two classes from this example should probably be inset-ring-black and inset-ring-white, together with all the following classes.
