fix(deps): widen click constraint from ~=8.1.7 to >=8.1.7,<9

Fixes #6002. The previous click~=8.1.7 constraint (>=8.1.7,<8.2.0)
prevented users from upgrading to click 8.2+ as required by their
security policies. The codebase only uses stable click APIs (echo,
secho, confirm, prompt, group, command, option, argument) with no
custom ParamType subclasses, so widening to >=8.1.7,<9 is safe.

Updated in all three workspace members:
- lib/crewai/pyproject.toml
- lib/cli/pyproject.toml
- lib/devtools/pyproject.toml
