Clean-up old classes from the HTML

[andreslucena]

We have lots of unused classes in the HTML.

I have explained a (manual) way of doing the clean-up (see #11752) but @alecslupu found a way of automating it, so we're working on the clean-up on #12074

What we do is to make PRs against that same branch for each of the modules so its easy to review. When we finish with the process and all the linter errors are gone, then we'll merge that branch against develop.

For running the linter you need to change the module name on this command: erblint decidim-participatory_processes/app/views/**/*.erb

There are lots of examples of the removals in the related PRs
