feat(ui): add cURL command to execute window

[yuri1969]

What changes are being made and why?

• Provided just the UNIX shell version - no support for Windows CMD/PowerShell.
• Displayed the cURL command preview as it IMHO improves the UX - the user actually sees what is copied. However, it can easily be transformed to just the Copy as cURL button.
• The FILE input can't be really supported since browser doesn't have the full path.
• User credentials nor SECRET inputs should be presented.
• Componentized the copy-to-clipboard button.
• The French translation was done via Google Translate, sorry.

closes #3585

Thanks a lot! This is very great!

Before one of our frontend experts reviews it, may I propose some enhancements?

• For SECRET input type, you can add them with ****** as the value.
• For FILE input type, they are the more complex as we use specific handling, so it would be great to show how to works by considering files are in the current working directory, so if a user have an input myfile.txt it generates a curl that will upload the myfile.txt from the current directory.
• With these changes the WARNING cloud be updated to something like 'Note that for SECRET and FILE input type, the command must be accommodate to match the real values'.
• Can you remove the Transfert-Encoding header, it is not mandatory
