Add support for logs

[ahayworth]

This commit adds support for generating a single otel log line, based on
upstream's beta support for logs. Currently, this change only supports
generating a single log line. It does, however, seem to work:

otel-col  | 2024-07-22T15:31:55.338Z    info    LogsExporter    {"kind": "exporter", "data_type": "logs", "name": "debug", "resource logs": 1, "log records": 1}

In addition, this PR updates various dependencies in order to make
golang happy. We use a newer golang version in general, and update to
the latest released versions of the APIs and SDKs for otel (logs, and
metrics). This required a few renames, but nothing substantial.

I have no idea what the linter is complaining about now :(

level=warning msg="[runner] Can't run linter goanalysis_metalinter: buildir: failed to load package : could not load export data: no export data for \"cmp\""
  level=error msg="Running error: can't run linter goanalysis_metalinter\nbuildir: failed to load package : could not load export data: no export data for \"cmp\""

Thanks for submitting code to the project. I finally had a chance to revisit the tool and have added logs. it'll emit over OTLP gRPC and HTTP. So far mostly done testing locally using Loki as per screenshot.

Have also done a big update to traces and metrics too.

Fantastic, thank you! I'll close this as not needed then. 😄
