Missing docstring examples for `to_date`, `to_time`, and `to_local_time` in scalar temporal functions

[kosiew]

Description

#1424 added examples for several temporal functions, but some public wrappers in the same section still do not have examples.

• Add docstring examples for Scalar temporal functions #1424 (comment)

Specifically, the following functions are missing docstring examples:

• to_date
• to_time
• to_local_time

These functions appear alongside other scalar temporal functions that now include examples, so their absence makes the documentation feel incomplete.

Expected Behavior

All public scalar temporal wrapper functions in this section should include usage examples in their docstrings, consistent with the rest of the temporal functions.

Suggested Improvement

Add simple usage examples to the docstrings of:

• to_date
• to_time
• to_local_time

following the same style used by the other scalar temporal functions.
