rm gem name from external gemfile

[QWYNG]

Hi! thank you for great gem!
I tried to work on this issue, but when I specified devise as the downstream dependency codebase for omniauth, I got the following error.

config/external.yaml in omniauth

devise:
  url: https://github.com/heartcombo/devise.git
  command: bundle exec rake test

≻ bundle exec bake test:external

Your Gemfile lists the gem omniauth (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once.
While it's not a problem now, it could cause errors if you change the version of one of them later.

[!] There was an error parsing `Gemfile`: You cannot specify the same gem twice coming from different sources.
You specified that omniauth (>= 0) should come from an unspecified source and source at `../..`
. Bundler cannot continue.

This PR adds a process to remove potentially duplicate Gemfile lines.
Gemfile generated as a result of testing with omniauth with this process added is as follows.

I'm generally okay with this, but I'm a little concerned it's fragile. However, it's not critical it breaks.

@ioquatix
Thanks for the merge. and
Thank you for changing it to a better code.
However, does the c8deb63 change overwrite the command variable in bake/test/external.rb:87?

[ioquatix]

Ohhh yeah it does, haha, totally missed it. Let me fix it. Thanks for checking it.
