chore: Update EOC slack channel reference

Why is this change being made?

Provide a detailed answer to the question on why this change is being proposed, in accordance with our value of Transparency.

Please add the details saying why, not just what in this section. Example: We have discussed the topic in Slack - (copy of Slack conversation). The current process is not efficient, this MR makes the description of X more clear, and helps move Y forward.

I was looking at our Incident Management page and realised there was an outdated reference. This is a small MR to fix it.
