Pre-bug-report checklist

1. This bug can be reproduced using pure Argo YAML

• Yes 👉 Please report a bug to the Argo Workflows GitHub 👈
• No

If yes, it is more likely to be an Argo bug unrelated to Hera. Please double check before submitting an issue to Hera.

Describe the bug
A clear and concise description of what the bug is:

Passing a list of Parameter to a DAG or Steps inputs gives a mypy linting error:

error: Argument "inputs" to "DAG" has incompatible type "list[hera.workflows.parameter.Parameter]"; 
expected "Inputs | hera.workflows.parameter.Parameter | hera.workflows.models.io.argoproj.workflow.v1alpha1.Parameter | hera.workflows.artifact.Artifact | 
hera.workflows.models.io.argoproj.workflow.v1alpha1.Artifact | dict[str, Any] | list[hera.workflows.parameter.Parameter | hera.workflows.models.io.argoproj.workflow.v1alpha1.Parameter | 
hera.workflows.artifact.Artifact | hera.workflows.models.io.argoproj.workflow.v1alpha1.Artifact | dict[str, Any]] | 
None"  [arg-type]

To Reproduce
