Currently there are following options for package manager when running crawlee cli:
Poetry
Pip
Uv
Manual

Selecting any of the options except for the manual will not only prepare the project files, but immediately also install the packages to whatever environment is currently active, which might not be desired. (What is the use case where this is actually desired?)

Add one more boolean cli option "install the project to current environment" which will follow after package manager selection and will control whether the post_gen hook installs the project or not.

(Maybe drop the manual option?)
