Auto formatting should be disabled by default

Description

After upgrading to ruby 2.7.6 our IRB got broken, copy and pasting a long string was slow, if you need to paste a multiline test in a middle of a string that also didn't work. We had to upgrade the IRB gem to 1.5.0, now it always automatically formats the output, which I don't need.

Now the output looks like this, which is quite annoying. Previously, when I needed a formatted output I was able to use pp. Can't find a way to disable this with Heroku also.

Another problem with truncation, while I understand the reason on large objects such as Array or Hash, doing this on AR instances like this

2.7.6 :006 > site = Site.find(523)
  Site Load (1.3ms)  SELECT  "sites".* FROM "sites" WHERE "sites"."deleted_at" IS NULL AND "sites"."id" = $1 LIMIT $2  [["id", 523], ["LIMIT", 1]]
 =>
#<Site:0x000000010b7f08a8
...

Just doesn't make any sense to me. And even on Arrays doing things like

2.7.6 :002 > stats = [[17144, 514], [17638, 522], ...]
 =>
[[17144, 514],
...

Is barely informative. It would make more sense to show Array(123), where 123 is the size of an array.
