[SEMANTIC CONVENTIONS] feat: semconv generate events

[proost]

Changes

I found that "exception" is missing.

"exception" itself is on the event not the attribute
.

So i add new template.

• CHANGELOG.md updated for non-trivial changes
• Unit tests have been added
• Changes in public API reviewed

LGTM, thanks for the feature.

Nicely done, integrates well with the existing code generation.
