Add trace ID injection into logs documentation

[willarmiros]

For each supported language, it would be great to have a section to document how to inject trace IDs into logs. I know this is straightforward w/ the ADOT Java Agent, but I'm less sure about its support in other languages. However even for the Java Agent, which does the heavy lifting of making trace IDs available to be injected to logs, customers still need to update their logging configuration to include trace IDs in log messages. This should be documented for easy customer discoverability, so that services like CloudWatch ServiceLens which use trace IDs to correlate logs can perform as expected.

Example of X-Ray docs for how to configure this:
