Updated installation instructions for the SDK.

Thanks for you contribution.

uv add ucp-sdk won't work if the pyproject.toml is not present. Can you add language around the dependency required to run uv-add?

If not just remove that instruction.

@aksbro-gpu

no uv add works fine even if we dont specify in pyprojecttoml

I think you misunderstood my comment.

Any user who is just following the instructions will run into an error if they are not in an initialized project directory.

Either you add "uv init" command before running "uv add ucp-sdk" or you add some verbiage that the command should run from an initialized project directory.

@aksbro-gpu get it, fixed
