Add more data to the compats table

[julioalucero]

This PR adds more data to the compats table in order to resolve this issue #118.

• compact.id was added in the first column.
• Rails Release was added in the third column.

We can move if we prefer.

Seed Data

I added a section to the Readme called seed data to help with local setup that is outside of the original issue's scope.
In parallel, I added Rails 8 to the list of Rails Releases

1. We do not necessarily need to add this, but also maybe the correct title is local setup.
2. I would keep the step 1 because when you set up locally, we need those Rails releases. step 2 and 3 are not necessary, given that they can be done by UI.

@etagwerker can you share with me the current Production values for Rails 8? I'll copy paste here.

According to our own blog post and rails' own gemspec it should be:

minimum_ruby_version: "3.2.0",
maximum_ruby_version: "3.4.2",
minimum_bundler_version: "1.15.0",
maximum_bundler_version: "2.5.20",
minimum_rubygems_version: "1.8.11"

Thanks @mateusdeap, I have doubts because on this file, for Rails 7.2, we have, for example:

minimum_bundler_version: "2.5.20"
