Slack app classic deprecation, can't add new bots since 06/06/2024

[bmalynovytch]

Describe the bug
Slack has deprecated the "Slack app (Classic)" bots, which prevents from adding new bridges with Slack.
See https://api.slack.com/changelog/2024-04-discontinuing-new-creation-of-classic-slack-apps-and-custom-bots

To Reproduce
Try to add a new Slack bot configuration with https://api.slack.com/apps?new_classic_app=1, as stated in the documentation (https://github.com/42wim/matterbridge/wiki/Slack-bot-setup#create-the-classic-slack-app)

Expected behavior
A new bot should be added.

Question: should the Wiki page be updated with new (working) instructions describing how to setup the bot or should the Slack codebase be completely rewritten ?

Well, i urgently need working instructions. Even if you dont update the wiki, can you hint me towards a solution? :)

Same for us, we can't link new teams anymore :(

It would be nice to have some instruction.

I, also would very much like to get this working. I have a slack workspace and I'm ready and available to test a beta version if there's something bleeding.
