Update the "#sales-support" Slack channel link on the Sales Operations page.
This updates the "#sales-support" Slack channel link at https://about.gitlab.com/handbook/sales/field-operations/sales-operations/ so it uses the channel URL that opens the desktop app if present.
Note: The page at that URL provides a link to the browser version of the channel page for those who need or want it.
