Loris: [Configuration] 'Date display format' input not changing date display

[CamilleBeau]

Describe the bug
Changing the settings for Date display format on the Study page of the configuration module does not change the date display format throughout the site.

To Reproduce
Steps to reproduce the behavior (attach screenshots if applicable):

1. Go to Configuration module
2. Change the date format in the Date display format at the bottom of the Study page
3. Save the option
4. Navigate throughout the site to find displayed dates
5. See error

What did you expect to happen?
Description of this option is The Date format to use throughout LORIS for displaying date information. I expected the format of the displayed dates such as DoB and EDC in the Access Profile page, etc to change when the format was modified.

This was added in #5004. The original post may be helpful here:

Following today's meeting, this adds a config option to allow projects to specify how they want dates to be displayed in LORIS.
This PR only adds two quick examples of using this Config setting; it is by no means comprehensive.
Also, this will only take place in "PHP contexts" and not within JS date elements as these are OS- and locale-dependent.

So this is happening not because of a bug but because this has not been implemented in all cases.

Thank you @johnsaigle! I can close this issue in favour of your more specific one then?

Sure that sounds good to me 👍 Thanks for opening this issue - hopefully we can get this fixed by the next release
