Deprecated reference: crewai[tools] locked to python-dotenv v1.0.0

[nikolaidk]

Because crewai[tools] (0.22.5) depends on python-dotenv (1.0.0) and no versions of crewai match >0.22.5,<0.23.0, crewai[tools] (>=0.22.5,<0.23.0) requires python-dotenv (1.0.0). So, because agentflow depends on both crewai[tools] (^0.22.5) and python-dotenv (^1.0.1), version solving failed.
