Fix debug exporter: render TraceID and SpanID as attributes

[Arunodoy18]

Description

The debug exporter was rendering TraceID and SpanID using logEntry, which caused
misaligned output compared to other fields rendered as attributes.

This change updates the debug exporter to render TraceID and SpanID using
logAttr, ensuring consistent formatting and column alignment with the rest
of the log output.

Link to tracking issue

Fixes #14471

Testing

• Updated golden testdata to reflect the corrected output format
• Ran go test ./...
• Ran go build ./...

Documentation

No documentation changes were required.

I cleaned up the branch, removed duplicated diffs, and force-pushed a single clean commit.
The fix now renders TraceID and SpanID consistently as attributes, and testdata has been updated.

Thanks for the review.

This pull request tries to make the same change as #14472, which I rejected as incorrect. What is the reason for this PR?

[Arunodoy18]

Thanks for pointing this out.

I wasn’t aware that #14472 was rejected for functional reasons.
My intent here was to address #14471 by making the TraceID and SpanID rendering consistent with other attributes, but I may be missing the design constraint that made the previous change incorrect.

Could you clarify what aspect of this approach is not desired, or what the correct direction should be for #14471?
I’m happy to adjust or close this PR accordingly.
