ref: bump slack-sdk to 3.40.1

[getsentry-bot]

I'd like to bump our slack-sdk version in sentry so we can use the new markdown blocks provided by the v3.40.0 of slack-sdk (github link).

This will help me with the development of Seer explorer via Slack mentions , as Seer returns text in markdown, not Slack's blockkit or mrkdwn.
