chore: widen click dependency to >=8.1.7,<9

Relaxes the click pin from ~=8.1.7 (which caps at <8.2.0) to >=8.1.7,<9.
This allows enterprise customers with InfoSec requirements for click 8.3.x
to install CrewAI without dependency resolution failures.

Click 8.1→8.3 has no breaking changes for our CLI decorator usage.
