feat(manager/bundler): support groups within source blocks

[mustardnoise]

Changes

This PR fixes the updating of gems from private sources with groups.

Context

I have a Gemfile with the private source and groups within this source.

source 'https://rubygems.org'

ruby '3.3.0'

gem 'rails', '~> 7.1'

source 'https://PRIVATE' do
  group :test do
    gem 'private_dummy', '~> 0.0.1'
  end

  group :production do
    gem 'another_private_dummy', '~> 0.0.1'
  end
end

It is currently not possible to update gems in the next group(s) within the private source.
