Bump Terraform from 1.0.11 to 1.1.6

[mctofu]

This is a minor release from our last version and includes some new features.

https://github.com/hashicorp/terraform/blob/v1.1/CHANGELOG.md#116-february-16-2022

This update triggered a test failure:

 1) Dependabot::Terraform::FileUpdater#updated_dependency_files when using a lockfile that requires access to an unreachable module raises a helpful error
     Failure/Error:
       expect { subject }.to raise_error(Dependabot::PrivateSourceAuthenticationFailure) do |error|
         expect(error.source).to eq("github.com/dependabot-fixtures/private-terraform-module")
       end

       expected: "github.com/dependabot-fixtures/private-terraform-module"
            got: "git::https://github.com/dependabot-fixtures/private-terraform-module.git"

       (compared using ==)
     # ./spec/dependabot/terraform/file_updater_spec.rb:905:in `block (4 levels) in <top (required)>'
     # /home/dependabot/dependabot-core/common/spec/spec_helper.rb:49:in `block (2 levels) in <top (required)>'
     # ./.bundle/ruby/2.7.0/gems/webmock-3.14.0/lib/webmock/rspec.rb:37:in `block (2 levels) in <top (required)>'

I've addressed this by stripping the git::https:// and .git from git::https://github.com/dependabot-fixtures/private-terraform-module.git to match the previous behavior. It might be possible to see other prefixes like git::ssl:// but the handling of this error is only concerned with https access so I'm allowing other prefixes to pass through unchanged.

The test failure might be related to #4440

It's strange to see the error source change though, since we should only ever change the name.

Thanks! I left one nit about extracting a constant but feel free to ignore that as you see fit

I guess this could be a constant 🤷

👍 Went ahead and did this. I was debating this since moving the definition up to the top of the file could hurt readability. That does seem to be a more consistent practice in this repo though so I went with it.
