fix(standard-provider): convert all pendulum objects on virtualenv version mismatch

[Alwaysgaurav1]

Description

When using PythonVirtualenvOperator with pendulum<3 in the virtual environment while the host runs Pendulum v3, pickling/unpickling fails because Pendulum's internal representations are incompatible across major versions.

The existing _pendulum_to_native_datetime function only converts pendulum.DateTime objects to native datetime.datetime. However, other Pendulum types (Date, Time, Duration, Timezone) can also leak into serialized arguments and return values, causing AttributeError exceptions like type object 'Timezone' has no attribute '_unpickle'.

This PR extends both the host-side and guest-side conversion functions to handle all Pendulum types:

• pendulum.Date → datetime.date
• pendulum.Time → datetime.time
• pendulum.Duration → datetime.timedelta
• pendulum.tz.timezone.PendulumTimezone → zoneinfo.ZoneInfo or datetime.timezone

The guest-side _native_datetime_to_pendulum function in the Jinja2 template is also updated to convert the native types back to their Pendulum equivalents.

A new unit test test_pendulum_to_native_datetime_extended verifies all the new type conversions.

Closes: #50752
