Bug Fix: Month Selector and Week Selector

[alexandrevega]

There's a bug when altInput is true while using monthSelector or weekSelector.
Also, dateFormats are being forced on both, ignoring user's dateFormat().
I implemented a fix using same approach as https://github.com/savannabits/filament-flatpickr/blob/c1a74870e9056988ad001955ac7674c090f11ac0/src/Forms/Components/Flatpickr.php#L141C3-L143

However, this doesn't fix altInput, enabling this option while using weekSelector or monthSelector will make it crash as seen in #45 .
I'll take a deeper look into fixing altInput, as for now this should allow many people to use both features.

PR Summary 📝

• A Change in the Date Picker Function 🗓️
  We've made improvements to a function called flatpickrDatepicker which is found in the flatpickr.js file. What it does is simply give you better control over the format of the date on the user interface. These changes ensure that this function adapts better to the configuration of the project/platform it's being used on.

• Smart Date Formatting 🧠
  In a file called Flatpickr.php, we've added a smart feature that checks the format of the date. If the format contains the letter "d", the default format is set appropriately. This translates to a user-friendly experience where the date format automatically adjusts to what's most useful in the situation.

I'm very keen for this PR! Love this plugin - flatpickr is a great little utility for slightly non-standard date inputs, like week selects and date ranges. This PR makes the week select feature so much more usable, as I can then customise the output ("Week 1" doesn't mean much to my users, but "Week starting 2024-01-01" does, so I really want to use my own date formats!)

@alexandrevega I also took a look at the altInput issue - see #51.
