Bump "@google-cloud/firestore": "^6.5.0" to "^7.8.0"

[WianSnyman]

To prevent conflicts and warning during compile time, please bump the package dependency

From the command npm list @google-cloud/firestore when starting a fresh firebase node project, it is clear what needs to be bumped

A quick fix in the meantime would be to add an override to the firebase package.json

"overrides": {
  "firestore-storage": {
    "@google-cloud/firestore": "7.8.0"
  }
},
