fix(apollo-reporting-protobuf): added long to dependencies

[kiancross]

The code emitted by the protobufjs pbts tool includes the long dependency. This should be a peer dependency of protobufjs (done in apollographql/protobuf.js#6) and therefore also needs to be added to the dependencies of apollo-reporting-protobuf.

I was also looking into this because it breaks on yarn2 in PnP mode.

There's one caveat here though. apollo-reporting-protobuf does not even use the Long types, and it opts out of it via --force-number:

apollo-server/packages/apollo-reporting-protobuf/package.json

Line 10 in fe7df73

"pbjs": "apollo-pbjs --target static-module --out dist/protobuf.js --wrap commonjs --force-number dist/reports.proto",

However, https://cdn.jsdelivr.net/npm/apollo-reporting-protobuf@0.6.2/dist/protobuf.d.ts imports long on the first line, but doesn't use it anywhere else within (because of forcing number above).

I think the right fix would be to omit adding that import if Long types are opted out of in:

I opened apollographql/protobuf.js#7 which should make the changes in this PR unnecessary.
