Upgrade to Ruby 3.x

[yksflip]

as mentioned in #979 it's already time to upgrade the ruby version again ... ruby 2.7 is now EOL

• less-rails depends on therubyracer and seems not to support the newer mini_racer gem
  see: heroku deploy failing with therubyracer dependency metaskills/less-rails#160

ahh there's an issue for that already: #928
I'll give it a shot and try to convert the .less files to .scss

I found this for bootstrap: https://github.com/twbs/bootstrap-sass
But I think we have to upgrade to v3, in v2 smth seems to break with sass-rails and other gems ...

I know upgrading bootstrap sounds terrible, but I did a quick and dirty run and I think it's doable. Just touch every single view :o

sneak peek of the brokeness:

I am making good progress with updating Foodsoft to Ruby 3.x. However I've now encountered the first gem that is not compatible with Ruby 3.x as it seems: https://github.com/technoweenie/acts_as_versioned

Fixing it seems to be just changing one line, however the question would be if we should create a fork of the gem? I can try to create a PR but as this gem had no changes in more than 10 years, my hopes are not too high. There is also another fork, but it is also old and added other changes: https://github.com/mjsommer/acts_as_versioned/tree/master

Edit: I've looked for existing forks and found this one that adds Ruby 3.x support, will use it for now: https://github.com/assembla/acts_as_versioned

Based on this it seems that PaperTrail (and its gem repo) is de-facto a standard by the looks of it. I don't know what the differences are, though.

@RayOei Thanks! I think for just getting to Ruby 3 we should keep acts_as_versioned as a new gem would need us to cover a migration path for already created wiki pages with acts_as_versioned.
