fix: update slack test to point to new channel (#3328)
When we switched community Slack from Paid to Free we lost the CI test
bot. Also if messages delete after 90 days then our expected test data
will disappear.
- created a new bot in our paid company slack
(test_unstructured_ingest_bot)
- added a new private channel (test-ingest)
- invited the bot to the channel
- adjusted the end datetime of the test to cover the first few messages
in the channel
Still to do:
- update the CI secrets with the new bot token
- update the LastPass with the new bot token (I don't have write
access.. :(.
