Update rails requirement from ~> 3.0 to >= 3, < 8

[dependabot]

Updates the requirements on rails to permit the latest version.

Release notes

Sourced from rails's releases.

7.0.3

Active Support

• No changes.

Active Model

• No changes.

Active Record

• Some internal housekeeping on reloads could break custom respond_to? methods in class objects that referenced reloadable constants. See #44125 for details.

  Xavier Noria

• Fixed MariaDB default function support.

  Defaults would be written wrong in "db/schema.rb" and not work correctly if using db:schema:load. Further more the function name would be added as string content when saving new records.

  kaspernj

• Fix remove_foreign_key with :if_exists option when foreign key actually exists.

  fatkodima

• Remove --no-comments flag in structure dumps for PostgreSQL

  This broke some apps that used custom schema comments. If you don't want comments in your structure dump, you can use:

  ActiveRecord::Tasks::DatabaseTasks.structure_dump_flags = ['--no-comments']

  Alex Ghiculescu

• Use the model name as a prefix when filtering encrypted attributes from logs.

  For example, when encrypting Person#name it will add person.name as a filter parameter, instead of just name. This prevents unintended filtering of parameters with a matching name in other models.
