Fix links 404/302/303 in docs/community

[adrienbrunet]

Following Issue #6289 recommendations, I installed textlint with the rule textlint-rule-no-dead-link.

Here is the relevant output that I fixed with this PR. At the end, you can find the broken URLs found that I did not fix. I'm not sure what to do with those.

[rpkilby]

The kickstarter announcement is now under the "community" section instead of "topics".

I think https://hello.machinalis.co.uk/ should be https://www.machinalis.com/.

[adrienbrunet]

I fixed the documentation with your proposals @rpkilby
Doing so, I noticed some more dead links in https://www.django-rest-framework.org/community/kickstarter-announcement/#sponsors

I corrected divio.ch to divio.com and company.onlulu.com to onlulu.com

I'm not sure all of these companies still exist:

https://singinghorsestudio.com/
pulsecode.ca (Timed out. Is it https://www.pulsecodeinc.com/ ? )
https://www.nexthub.com/?so=1 (blank page)
https://wusawork.org/ (403)

I left their links as is.

[tomchristie]

Okay, shall we get this merged as-is then?
I guess the other option would be to drop the broken links completely, and just leave them as text.

[adrienbrunet]

I remove the href="..." parts when broken. Is that okay? Should this be merged now ?
(We could use an other tag than <a> but that would mean some more css etc... Not sure it's worth it)

Tell me if I'm wrong or need any more improvements. Cheers

.... and happy new year you all. ✨ 💖 🍾

[tomchristie]

Looks good to me. Thanks!
