Fix emotion label not being applied to components with numbers in name

[dcastil]

What:

Fixes emotion label in development not being applied to components with numbers in component name.

/** @jsx jsx */
import { jsx } from '@emotion/react'

// className: css-2a3l4r-MyComponent
const MyComponent = () => <div css={{}}  />

// className: css-fhsrqh
const MyComponentNo1 = () => <div css={{}}  />

Why:

Components with numbers in their name deserve the same love and recognition within the Elements tab in Chrome devtools!

How:

Adding numbers to the regex which is used to identify the emotion label.
