fix(semconv-ai): bump version to 0.4.16 for GenAICustomOperationName

[SanjanaB123]

Fixes #3814

Problem

LangChain instrumentation fails to initialize with traceloop-sdk 0.53.0
because GenAICustomOperationName was added to the local source of
opentelemetry-semantic-conventions-ai but the package version was not
bumped, so PyPI still serves 0.4.15 which is missing the symbol.

Fix

• Bumped opentelemetry-semantic-conventions-ai version from 0.4.15 → 0.4.16

• Updated opentelemetry-instrumentation-langchain minimum dependency
  from >=0.4.13 → >=0.4.16 to ensure the new symbol is always available

• I have added tests that cover my changes.
  (version bump only — existing tests already cover GenAICustomOperationName)

• If adding a new instrumentation or changing an existing one, I've added screenshots.
  (not applicable — this is a dependency version fix)

• PR name follows conventional commits format.

• (If applicable) I have updated the documentation accordingly.
  (not applicable — no docs changes needed)

Summary by CodeRabbit

• Chores
  • Updated opentelemetry-semantic-conventions-ai dependency to version 0.4.16, including matching internal dependency constraints.
