Datepicker is not using custom dateFormat from locale

[richard-schiemenz]

Reproduction link

Steps to reproduce

Wrap DatePicker in ConfigProvider with locale and dateFormat for DatePicker set.
Select a date in the DatePicker.

What is expected?

The date is formatted with the format specified in the locale.

What is actually happening?

The date is formatted with the default format.

Environment	Info
antd	5.4.6
React	9.6.2
System	macOS 13.3.1
Browser	Chrome 112.0.5615.137

I need to set the format of the date displayed based on the locale as I have multiple locales. I have tested modifying other values in the locale object and it worked as expected. Only modifying the dateFormat seems not to be working.
Other issues show a solution by setting the format in the DatePicker to "L" but this is a fix using moment and I want to stay with the now default dayjs.

I don't think this is the same issue, as there the problem lied in translating written days of the week. I had a similar issue and fixed it by importing the language files.
Here however the formatting is not applied. Which in the example doesn't use any written out weekdays but just the digits.

I'm sorry I was careless

@richard-schiemenz I'm sorry, but the official documentation doesn't seem to indicate that the locale={} provided by the ConfigProvider can be passed in with the dateForm parameter.

[richard-schiemenz]

@BoyYangzai the official example for the DatePicker locale has it listed. locale example Further it's the only date with the same format that is displayed.
From what I understand this is the right key and once worked in a previous version. It was added here #14340. There it was used with the LocaleProvider, but this was replaced by the ConfigProvider how I used it.

@richard-schiemenz
I'm sorry, I couldn't find the source code when I was looking through it before.
This may be a previous usage, I'm sorry.

@BoyYangzai Ok, thank you.
Maybe it should be removed from the example if it is no longer supported. As this example is linked to on the official documentation DatePicker Localization.
I updated the code sandbox to show the implementation with the locale directly input to the DatePicker as shown in the first example. It also doesn't apply the format.

I think it is indeed a bug.

Hey guys, looking at it to see it if I can contribute with a pr!

@richard-schiemenz The writing should be as follows.

[linhf123]

@Rafael-Martins You are at antd 4. * Have you used this function in the version?
I tried 4. * The version was found to be ineffective, and the code of antd did not support it here.

This is caused by the refactoring of rc-picker. If you are interested, you can contribute with a pr.

Oh cool, I was fixing my local environment. I will try to fix it today!

[Rafael-Martins]

I opened a pr with a solution, we can discuss about it in there!
