Slack links mismatch and invalid

[elfranne]

There are two different links to the Community Slack:

https://github.com/apache/cloudstack-www/blob/a8dfa72c0739e6f0c10e80c7da00c5013ac99df5/src/pages/index.tsx#L273

https://github.com/apache/cloudstack-www/blob/a8dfa72c0739e6f0c10e80c7da00c5013ac99df5/docusaurus.config.js#L124

and none of them works.

@elfranne the reason for this is that slack does not allow indefinate valid join links (as far as we have found so far, so it makes little sense to update them. The top one is the more recent. here is a new one: https://join.slack.com/t/apachecloudstack/shared_invite/zt-2h8hyf64k-VypssnZc5r3g1swuehmI_Q it will expire in 30 days :(
