Apparently intentionally removed by #709

I lack context here, @mikellykels?

@untitaker the actual decision to remove it from the docs was done in Slack, but this is the Jira ticket that started the whole discussion on supporting SessionStack https://getsentry.atlassian.net/browse/ISSUE-135.

A little more context here https://getsentry.atlassian.net/browse/FEEDBACK-261, but basically the integration had been broken for 6+ months and SessionStack were the ones maintaining it.

@mikellykels I had a conversation with them earlier today, tested the integration, and it works. Their docs aren't up-to-date either, so a small modification was required, but other than that, nothing seems amiss.

@mikellykels We fixed the integration a few months ago because we broke it. I think if we want to remove it from our docs we should also remove it from marketing pages. Who made the call on removing it?

Fixed the broken link on https://sentry.io/integrations/sessionstack/ to redirect to SessionStack's docs
