Garden install instructions hang on dependency installation command

It appears that in https://gazebosim.org/docs/garden/install_ubuntu_src

Source:

https://github.com/gazebosim/docs/blob/master/garden/install_ubuntu_src.md#install-dependencies

The $(find . -iname 'packages-'lsb_release -cs'.apt' -o -iname 'packages.apt') returns empty. Which then the sort -u will hang waiting for an input.

I believe that there's an unwritten assumption about what path you're executing in. You need to be in the directory of the workspace with the checked out code.

I've opened a draft PR to clarify the working directory needed for this step: #398
