Typescript export: characters in event names not escaped

[josephfh]

The issue: Apostrophes (and perhaps other characters) are not escaped in the types of both v4 and v5 Typescript export code

Example machine:

Example output (see the types:)

import { createMachine } from 'xstate';

export const machine = createMachine({
  "id": "Untitled",
  "initial": "Rock?",
  "states": {
    "Rock?": {
      "on": {
        "let's rock": {
          "target": "Roll"
        }
      }
    },
    "Roll": {
      "on": {
        "let's roll": {
          "target": "Rock?"
        }
      }
    }
  },
  "types": {events: {} as {type: 'let's rock', } | {type: 'let's roll', }}
}, {
  actions:   {},
  actors:   {},
  guards:   {},
  delays:   {},
})
