feat: Exchange students info page

[soderholmhugo]

Is your feature request related to a problem? Please describe.

It has been requested from the board of 2024 that we create a introductory page with information specifically for exchange students. This page would provide info about e.g. what DaTe is, who the current exchange tutors are, how they can contact the board/tutors, which rights/responsibilities exchange students have if they want to become members of DaTe, steps on how to become members, how to sign up for and view upcoming events, etc. Basically a DaTe handbook for exchange students.

Describe the solution you'd like

A new page that is easily accessible/viewable on the website, preferably always visible in the navbar header (not in a dropdown) so that exchange students can find it immediately when they enter the website. This can later be changed when we have the website available in english.

Additional context

• Something about inclusivity, particularly for exchange students, should be mentioned on this page. Short quotes/stories of former exchange students' experiences with DaTe and ÅA would be a nice addition
• The page only has to be in english
• Until the entire website is available in english, there could be a notice somewhere on this page telling people that the translated version of the DaTe website will be released in the near future

This should be done as a static page for now through admin, Once we add translations this can be re-implemented
