Update evaluation command in README

[ItsTania]

Currently - the template makes a few ridged assumptions.

For example with [project] \n name = "eval_name" in the .toml file and scr/"eval_name". If eval_name is not the same the docs are no longer accurate:

With Generality-Labs#1 :

@task calls get_installed_package_name(), which only resolves to a package prefix when an installed distribution exists by that name. If [project] name is e.g. "lab-bench" but the package folder is lab_bench_2, no distribution matches the import name, so the task is registered under its bare name (lab_bench_2) instead of the namespaced form (lab_bench_2/lab_bench_2).

A long-term solution would be to simplify this template - for now, this PR updates docs

Note: if loading through the full file path e.g src/lab_bench_2/lab_bench_2.py@lab_bench_2 is fine then we can remove all of the hassle of registering tasks etc etc.
