website link check fail due to external website

[lahabana]

          I'm aware of this CI failure on the link checker: 

https://github.com/kumahq/kuma-website/actions/runs/12921742840/job/36036265367?pr=2153#step:6:49

I'm merging this PR bypassing the link check as we need more discussion on how to deal with these link-checking errors:

https://deploy-preview-2153--kuma.netlify.app/docs/2.8.x/production/cp-deployment/zoneproxy-auth/
	500	https://jwt.io/
https://deploy-preview-2153--kuma.netlify.app/docs/2.7.x/policies/meshproxypatch/
	lookup jsonpatch.com on 127.0.0.53:53: no such host	https://jsonpatch.com/

Research:

• jwt.io is asking for a header -H 'accept-language: en-US'
• We need to find a replacement of jsonpatch.com as it looks like down permanently

For jsonpatch.com could we use: https://en.wikipedia.org/wiki/JSON_Patch ?

We can always set the header accept-language is common enough

Triage: Let's set accept-language all the time
