Typo in single-spa-leaked-globals code example

[Rajasegar Chandran]

The example for unmount array shows including leakedGlobalsLifecycles.mount, instead it should be
leakedGlobalsLifecycles.unmount in here, https://single-spa.js.org/docs/ecosystem-leaked-globals/

export const unmount = [
  leakedGlobalsLifecycles.mount,
  // Make sure leaked globals lifecycles' unmount function is **after** other lifecycles' unmount
  // This is so the global vars are still available during the framework unmount lifecycle function.
  frameworkLifecycles.unmount,
]

Expected behavior

export const unmount = [
  leakedGlobalsLifecycles.unmount,
  // Make sure leaked globals lifecycles' unmount function is **after** other lifecycles' unmount
  // This is so the global vars are still available during the framework unmount lifecycle function.
  frameworkLifecycles.unmount,
]
