Bump up pino-std-serializers dependency

[al-bglhk]

It's been several versions since pino-std-serializers was aligned with pino

I have updated the test case so it will now refer to request.socket instead of request.connection.
And skipped tests that expect request.connection (now request.socket) to be undefined, because request.socket is always available.

• request.connection has been deprecated since Node13
• request.socket interface is compatible with request.connection since v0.3.0, or at least v10

@jsumners did you recall why we did not bump this?

@jsumners did you recall why we did not bump this?

Likely because it is a major version increase or we just didn't think about it. But, it being a major version increase, I wonder if this PR should target v7?

It's just a drop of old node.js versions: pinojs/pino-std-serializers#40.
