Inaccuracies in README.md

Description

1. In Quickstart, the npm package @highflame/zeroid does not exist. I believe it should point to @highflame/sdk.
2. In step 1 of the 5 minute tutorial we import from the nonexistent npm package, that should also be updated.
3. There are several references to a ghost function "build_jwt_assertion", this does not appear to exist in ZeroID.
4. In step 2 of the 5 minute tutorial (Delegate to a Sub-Agent). We do not have an example in typescript, only python.
5. The python example in step 2 references a variable 'sub_agent_private_key', but it is not shown how this is generated. If external libraries are needed to generate the keys, we should also list them in the quickstart guide.
