chore: bump semconv 1.31.0

[lalitb]

Changes

We cannot bump weaver to latest (0.13.2) because something changed in the format of the notes and requires update in the jinja templates. This can be handled in next update. Current:

SPEC_VERSION=1.31.0
WEAVER_VERSION=v0.13.0

Merge requirement checklist

• CONTRIBUTING guidelines followed
• Unit tests added/updated (if applicable)
• Appropriate CHANGELOG.md files updated for non-trivial, user-facing changes
• Changes in public API reviewed (if applicable)
