[SLACK] Add files.delete Method

The idea is:

Add the files.delete method: files.delete method | Slack

My use case:

To auto archive uploaded image files when older than 31 days, in a certain channel.

I think it would be beneficial to add this because:

It’s a bit fiddly to try and do it via the HTTP node

Any resources to support this?

Are you willing to work on this?

Not in my skillset!
