Datetime dependent error when creating pipeline

### Describe the bug

Trying to create a job using `az ml job craete -f hello_pipeline.yaml` where hello_pipline.yaml contains (modified from an example found [here](https://learn.microsoft.com/en-us/azure/machine-learning/reference-yaml-job-pipeline?view=azureml-api-2)):

```yaml
$schema: https://azuremlschemas.azureedge.net/latest/pipelineJob.schema.json
display_name: hello_pipeline
type: pipeline
inputs:
somevariable: "2023-01-01T00:00:00Z"
jobs:
hello_job:
command: echo "hello"
environment: azureml:AzureML-sklearn-1.0-ubuntu20.04-py38-cpu@latest
compute: computename
world_job:
command: echo "world"
environment: azureml:AzureML-sklearn-1.0-ubuntu20.04-py38-cpu@latest
compute: computename
settings:
default_datastore: datastorename
```
the below error is thrown even though the created pipeline runs successfully in Azure Machine Learning. The error disappears when the value of somevariable is changed to "2023-01-01 00:00:00Z" with the pipeline still running successfully. This behaviour is independent of the name of the variable (somevariable here).

### Issue script & Debug output

I did not add debug output since it is really long and I don't want to go through the whole thing to remove sensitive information at this point.

### Expected behavior

Creation of the pipeline should work when using the date time format "YYYY-mm-ddThh:mm:ssZ". However, why are variables under inputs parsed for datetime formats irrespective of their variable name?
