Fix updaterun API syntax in tutorial and examples

[RomeoV]

Summary

Fixes incorrect positional argument usage and string type for the status parameter in updaterun function calls.

Changes

• Fixed docs/src/tutorial.md:112: Changed updaterun(mlf, exprun, "FINISHED") to updaterun(mlf, exprun; status=RunStatus.FINISHED)
• Fixed examples/simple-with-mlflow.jl:61: Applied same correction

Problem

The tutorial and examples used incorrect syntax:

updaterun(mlf, exprun, "FINISHED")  # ❌ Wrong

But the actual method signature requires keyword arguments and enum types:

updaterun(instance::MLFlow, run::Run; status::Union{RunStatus.RunStatusEnum,Missing}=missing, ...)

Solution

Updated to correct syntax:

updaterun(mlf, exprun; status=RunStatus.FINISHED)  # ✅ Correct

Impact

• Fixes MethodError that users encounter when trying to complete runs
• Fixes type error from passing string instead of RunStatus enum
• Makes the tutorial examples functional for run completion
• Resolves the final step of the tutorial workflow

Test plan

• Verified method signature using julia --project -e "using MLFlowClient; methods(updaterun)"
• Confirmed RunStatus.FINISHED is the correct enum value
• Both tutorial and example files updated consistently

Fixes #64

Actually this also fails if we don't provide run_name again. This is probably a bug aswell.
