Hey,
I would like to use a string-block value during the flow configuration. How would I do that?

What I have tried so far:
```@flow(
    name="Create Experiment",
    task_runner=DaskTaskRunner(
        cluster_class="dask_jobqueue.SLURMCluster",
        cluster_kwargs={
            ...
            "job_script_prologue": [
                String.load("log-slurm-job").value,
            ],
        },
    ),
)
def my_flow():```
But this will not build a deployment because the load was not `awaited`. What would be the correct way to use blocks for flow-configurations?

This works for me:
```from prefect import flow 
from prefect.blocks.system import String 

@flow(name=String.load("test").value)
def my_flow():
    ...

if __name__=="__main__":
    my_flow()```

I wonder if it has something to do with using DaskTaskRunner

Hmm I see. It doesn’t work when it is deployed

But interesting that deployment works for you. Even if I use the block for the flow name
```@flow(
    name=String.load("test").value```
 I get `RuntimeWarning: coroutine 'Block.load' was never awaited` when I run `prefect deployment build ...`.

I can wrap `String.load("test").value` into a `async`function and await the result inside it. Then the deployment works, but when I run the deployment it hangs forever (waited for 10min and then killed it).

This is a bug and we will solve it with <https://github.com/PrefectHQ/prefect/pull/7417|this PR>
