[docs] Remove instructions for submodules (#16650) Running `git submodule update` from the root of this repository no longer has any effect because the project no longer defines any valid git submodules at the top level. The commit referenced in these instructions was created over two years ago. Such an extended duration reduces the relevance of these instructions for a general audience. Those who are interested in working with such a dated revision will recognize that project installation instructions change with time, and they will find the relevant instructions in the corresponding revision of this document.
