Always use DateTime.ToString() instead of implicit casting to use current culture instead of invariant one

[Indigo744]

When converting a DateTime to a string, if ToString() is not explicitly called then Powershell use the invariant locale (en-us) instead of the current locale.

For instance on my machine (with French culture fr-fr):

> "$(Get-Date)"
02/09/2024 22:29:36 # mm/dd/yyyy

> "$((Get-Date).ToString())"
09/02/2024 22:31:40 # dd/mm/yyyy

More information here: https://jhoneill.github.io/powershell/2022/03/06/DateFormats.html

So in order to respect the current locale, ToString() must be call.

Thank you. As I plan for V3, this may come useful.
