Add build docs to README #39
Description
Is your feature request related to a problem? Please describe.
It is not clear from the README how to build the repo from source for use as a dependency. We only have local build instructions.
Describe the solution you'd like
Add a section for building from source and even an example for using after built from source. Also make it clear that users must clone recursively because temporalio/bridge/sdk-core is a git submodule.
