:sparkles: (#576): Added the climate change ai card to external res

[KAUR1984]

Fixes the issue #576. Related discussion in https://github.com/ACCESS-NRI/access-hive.org.au/pull/674.

--EDIT 21.05.24:

• [x] change title to "External Resources"
• [x] change the link to point to the ClimateAI general website, not to the tutorials
• [x] Make the link more visually appealing (Possibly with an image and a one liner description of the resource)
• [x] Change the description of the page to reflect what is actually in the page (something like "here's a list of resources not actively supported or maintained by ACCESS-NRI that can be useful to the ACCESS community"
• [x] Add "External Resources" card in the parent page (Community Resources) to point to this page

--EDIT 06.05.24

This is a new draft layout for adding external links and tutorials, subject to discussion in the Hive docs meeting. :)
