Slack SDK fails on large file uploads

[aiell0]

Describe the bug
/usr/local/lib/python3.9/site-packages/slack_sdk/web/internal_utils.py:450: UserWarning: client.files_upload() may cause some issues like timeouts for relatively large files. Our latest recommendation is to use client.files_upload_v2(), which is mostly compatible and much stabler, instead.

To Reproduce
Steps to reproduce the behavior:

1. Have a k8s cluster with a lot of stuff on it.
2. Attempt to use krr with a slack sink to send cost reports to Slack.

Expected behavior
The file should be in my slack channel.

Additional context
Slack looks like they fixed this in their latest release. So theoretically all one should need to do is update the dependencies and it should work.
