Dead links: Dutch vacature links to /vacature-commissie-website && /workshops lead to a "soft 404"

[immerMeer]

Describe the bug
On the Dutch version of the website, the https://www.fronteers.nl/nl/vereniging/vrijwilliger-worden page lists links to /vacature-commissie-website and /workshops. These pages, however, lead to a "Computer zegt nee!" page.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Vrijwilliger worden' page
2. Click on 'Commissie Website'
3. Land on "Computer zegt nee!" page

Expected behaviour
Either:

• Removal of links to fulfilled or non-existant volunteer application pages
• Presence of aforementioned pages, with all relevant information present

Additional context
On the English version of the website this issue seems not applicable
