Fix heroku 1 click

[aapomm]

Spec

Errors for 1 click deploy:

app[web.1]: fatal: not a git repository (or any parent up to mount point /)
app[web.1]: Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
app[web.1]: NOTE: nokogumbo: Using Nokogiri::HTML5 provided by Nokogiri. See https://github.com/sparklemotion/nokogiri/issues/2205 for more information.
app[web.1]: Could not find server "". 
app[web.1]: Run `bin/rails server --help` for more options.

This seems to be caused by the Ruby 3 removing Webrick as a bundled gem. Previously, the deployed app uses Webrick by default when being deployed.

Proposed solution
The solution I went with is moving the Puma gem outside of the development group in the Gemfile allowing it to be installed and used on deploy.

Copyright assignment

Collaboration is difficult with commercial closed source but we want
to keep as much of the OSS ethos as possible available to users
who want to fix it themselves.

In order to unambiguously own and sell Dradis Framework commercial
products, we must have the copyright associated with the entire
codebase. Any code you create which is merged must be owned by us.
That's not us trying to be a jerks, that's just the way it works.

Please review the CONTRIBUTING.md
file for the details.

You can delete this section, but the following sentence needs to
remain in the PR's description:

I assign all rights, including copyright, to any future Dradis
work by myself to Security Roots.
