Slack plugin gets truncated at 4000 chars

When the content goes over that 4k threshold, it gets split into another message which breaks the escape sequence.

During the rest call, we are currently using the text property but there seems to be a way to enrich messages via blocks (which seems to be the successor of attachments).

We should take a look at if using a block instead of the fallback text would fix the issue and update the plugin accordingly.

I've tried blocks and although they work they have some limitations

• Do not take the full width of the Slack channel viewport, which affects to our content since it overflows over it
• It has even a stricter size limit (2000 chars)

I tested spliting our output in sections (overview, materials, env vars) making them different blocks but that's also subject to size limit so it doesn't help.

I tested sending tables in markdown instead but Slack doesn't support markdown tables

So my take would be to do a specific Slack output, not to rely on our table helper. This custom output will leverage blocks but dynamically, for example a block per material and so on. That will skip the limit issue (up to 100 blocks)
