BUG: Broken link on Astropy page

[pllim]

This is a follow-up of #207. On https://www.pyopensci.org/communities/astropy.html , when I click on "partnership" (see first screenshot), I am taken to https://www.pyopensci.org/communities/partners.html that suggests the page I am looking for does not exist (see second screenshot).

@pllim great catch! Are you open to submitting a pr to fix this link? It should go here:

https://www.pyopensci.org/partners.html
