DEVREL-2731: Use display names for examples

[tim-webflow]

Builds on #59.

Separates each example into display name and code so we can put in a clear display name and filter out the wrapper function.

This requires changes to how we put examples in there. Now they are formatted like this; each example has a displayName and code element:

export const Elements = {
  // Element Management
  elementManagement: {
    getSelectedElement: {
      displayName: 'Get selected element',
      code: async () => {
        // Get Selected Element
        const element = await webflow.getSelectedElement()

        // Print element info
        if (element) {
          console.log(element)
          console.log(`Element type: ${element.type}`)
        } else {
          console.log('No element is currently selected.')
        }
      },
    },

Also fixes the bugs where the function wrapper is shown and the indents are off:
