Cloud Tasks 'package.json' has non-working 'exports' for 'protos'

[kalleprymne]

Issue with: @google-cloud/tasks to v5.5.1

After PR #5696 was merged, it's no longer possible to import 'protos'.
Neither the previously working import:

import { google } from '@google-cloud/tasks/build/protos/protos';

...nor the assumed migrations works:

import { google } from '@google-cloud/tasks/build/protos';

I believe this is due to 'package.json' needs an update in the 'exports' section and that the following lines:

https://github.com/googleapis/google-cloud-node/blob/tasks-v5.5.1/packages/google-cloud-tasks/package.json#L26-L35

...should be updated similar to this (or if wanting to keep old module path "./build/protos/protos" for backwards compatibility?):

  "exports": {
  ...
    "./build/protos": {
      "import": {
        "types": "./build/protos/protos.d.ts",
        "default": "./build/protos/protos.js"
      },
      "require": {
        "types": "./build/protos/protos.d.ts",
        "default": "./build/protos/protos.cjs"
      }
    }
  },
