Language preference in participant settings

Is your feature request related to a problem? A clear and concise description of what the problem is.

As a user it is not clear that selecting another language to browse the site updates my user preference.

As a user I want to be able to choose the language in which I will receive my email notifications.

Describe the solution you'd like

Given I'm a logged in user

I can visit my account page by clicking on my user name in the nav bar

Then I can see my language preference along with a text explaining this language is the one used to load the website.

Then I can select another language using a dropdown menu and clicking on the Update account. Doing so will reload the page in the language selected.

By default the associated language will be the one configured in the user's browser or the one set by the parameter in the url ?locale=

Given I'm a logged in user

I can visit my account page by clicking on my user name in the nav bar and then click on the notification settings tab.

Then I can choose with a dropdown menu the preferred language to receive my email notifications.

By the language is the same as the preferred language to browse the site

I need to click on "Save changes" to update my language preference for notifications

Additionnal context

We've added the notification preferred language as we need it to work on this proposal "Use machine translation in notifications".
