fix: loosen dependency constraints to fix OPIK integration conflict

This commit addresses issue #4201 where crewAI's overly restrictive
dependency constraints (using ~= operator) caused conflicts when
installing alongside packages like opik.

Changes:
- Changed dependency constraints from ~= (compatible release) to >=
  (minimum version) for core dependencies in crewai and crewai-tools
- Key dependencies loosened: openai, pydantic, pydantic-settings,
  opentelemetry-*, and others
- Added tests to verify dependency constraints remain flexible

The ~= operator was too restrictive as it only allows patch version
updates (e.g., openai~=1.83.0 means >=1.83.0,<1.84.0). This caused
dependency resolution failures when other packages needed different
versions of shared dependencies.

Fixes #4201
