Update dependencies and addopt cruft to get updates from the cookiecutter template

[bruno-fs]

After 10 months of inactivity, we are back!

However, before pushing new features we need a little bit of housekeeping:

• Update dependencies
• Fix broken tests
• Inherit changes from cookiecutter template (I decided to create a fork of "hypermodern python" with most customizations I did here and in other projects).
  • To "easily" inherit those changes cruft was added to the project. The adoption was not so smooth and I had to to solve some conflicts (with the help of another tool called rejx the process was less tedious than it may sound). This first step was very manual, but I intend to have a scheduled GitHub Action routine that fetches updates and opens PRs here.
• Make some code changes to adjust to updated linting rules.
