Discord log generation for `next` release

[asvae]

Should be done after or in context of #1987

Right now we have a release-script.ts, that handles release procedure. There we have next release type.

• We want this release automatically report in discord. There should be a separate channel for that.

Only next releases should be automatically reported. monthly and weekly releases we'll automate manually. For experimental there is no plan to have a log channel.

• Please document this logic in release-script.md and in notion when you're done.
