feat: Add round_trip=True as a default json serialization.

[pesap]

Some Pydantic models have computed fields (see example below) that should not be serialized. By default, .model_dump() includes these fields, which can cause deserialization errors since Component does not accept extra arguments.

The example below shows an example of a computed field that it is only meant to be used at run-time

from infrasys.component import Component

class TestComponent(Component):
    a : int
    b : int

    @computed_field
    @property
    def sum_a_b(self) -> int:
        """Create attribute that holds the class name."""
        return self.a + self.b

If we serialize using TestComponent using .model_dump(), sum_a_b is included, leading to errors when loading JSON. Setting round_trip=True in .model_dump() ensures computed fields are excluded from serialization.
