feat(postgrest): use Date when filtering columns

[LucasAbijmil]

What kind of change does this PR introduce?

When using filters on Timestampz typed columns, the Date.now.description declaration only works for users with time in 24-hour format and not for those using 12-hour one.
This pull request makes using filters simpler and less error-prone when manipulating the Date type.

What is the current behavior?

In order to use filters with Date type, we need to have a custom logic in order to make it works properly.

What is the new behavior?

When using a filter, the Date.now (or Date()) works by the book without having to implement a custom logic.

Additional context

If my change doesn't work on other Date/Time types, please let me know. I would be happy to make this works for everyone and every Date/Time type

That is a very good improvement, let me make a few tests using other time/date types to see how it behaves.

Thank you very much! I hope we can find a solution to make things easier for everyone :)
