Fix dependencies for surprise example

[nate-mar]

Encountered the following errors while trying to build/run the surprise example:

Because surprise-travel depends on install (^1.3.5) which doesn't match any versions, version solving failed.

Updated to pip-install. see (eugenekolo/pip-install#4) and (pypi/support#451)

Because crewai[tools] (0.85.0) depends on crewai-tools (>=0.14.0)
 and no versions of crewai match >0.85.0,<0.86.0, crewai[tools] (>=0.85.0,<0.86.0) requires crewai-tools (>=0.14.0).
So, because surprise-travel depends on both crewai[tools] (^0.85.0) and crewai-tools (^0.4.6), version solving failed.

Updated the crew ai tools version.

Should address #209
