Possible typo in the `build` instructions.

[YoelMonsalve]

I think there can be a typo in the instruction:

pip install conan<2.0

related to installing conan https://opensees.github.io/OpenSeesDocumentation/developer/build.html#ubuntu

To prevent bash from interpreting the < character as output redirection, might be good to type instead:

pip install "conan<2.0"

or, to specifically refer to Python3 (in case that Python2 is also installed):

pip3 install "conan<2.0"

Gladly,
Yoel.-
