Planning Major Version Update for notify_slack Due to Slack API Changes

[catatsuy]

Hello everyone,

We need to address significant updates required by the upcoming changes in the Slack API that will impact our notify_slack CLI client. The current files.upload method will be retired in March 2025 and replaced by new sequenced Web API methods, as outlined in the latest Slack documentation here: files.upload retires in March 2025, replaced by sequenced Web API methods.

These changes necessitate substantial modifications to how our client handles file uploads. Due to the extensive nature of these updates and their compatibility implications, we are planning to release a new major version of notify_slack.

This major update will help ensure that our client remains functional and efficient. Your support and understanding as we proceed with these changes are greatly appreciated. Feel free to share any thoughts or suggestions.

Thank you!

The removal of the channel parameter and the requirement to use only channel_id has broken our compatibility.
