fix: use compatible syncpack configuration

[JamieMason]

Fixes #923

• Update .github/workflows/syncpack.yaml to use the same major version as package.json
• Removes "sameMinorNew": true config (does not exist in syncpack)
• Migrate config and commands to v14 (https://syncpack.dev/guide/migrate-v14/)

The below line of .github/workflows/syncpack.yaml installed the latest major version unconstrained, and a major semver breaking change update had been released since the time of writing.

google-cloud-node-core/.github/workflows/syncpack.yaml

Line 18 in 7feb4c8

- run: npm install -g syncpack

I hope this helps, thanks for trying syncpack.

The syncpack errors are genuine according to the current configuration, which is asking that dependencies be on the same MAJOR.MINOR but any PATCH:

protobufjs for example is used on 7.5 and 7.0

   5x protobufjs
      ✘ ^7.5.4 in packages/gax/package.json at .dependencies (SameMinorMismatch)
      ✘ ^7.5.4 in packages/nodejs-proto-files/package.json at .dependencies (SameMinorMismatch)
      ✘ ^7.5.4 in packages/proto3-json-serializer-nodejs/package.json at .dependencies (SameMinorMismatch)
      ✘ ^7.0.0 in packages/proto3-json-serializer-nodejs/samples/package.json at .dependencies (SameMinorMismatch)
      ✘ ^7.0.0 in packages/gax/test/test-application/package.json at .dependencies (SameMinorMismatch)

Others like puppeteer are flagged because a range of ^ would allow MINOR versions other than 24.0 to be installed.

   1x puppeteer
      ✘ ^24.0.0 → ~24.0.0 in packages/google-auth-library-nodejs/samples/puppeteer/package.json at .dependencies (SameMinorOverridesSemverRange)

I don't have enough knowledge about what policies you would want to use to be able to help much further, sorry. There is a getting started guide at https://syncpack.dev/ and docs on the different policies available at https://syncpack.dev/version-groups/.
