"Bundle install" will not install gems from Github

[gerardbm]

I'm using Ruby 3.3.0 and Jekyll 4.3.3, with rbenv 1.2.0-87-ge8b7a27 and bundler 2.5.6.

When I run the command 'bundle install' I get an error.

This: gem "minima", git: "https://github.com/jekyll/minima.git"

Returns this:

And this: gem "minima", :git => "git://github.com/jekyll/minima.git"

Returns this:

The git source `git://github.com/jekyll/minima.git` uses the `git` protocol, which transmits data without encryption. Disable this warning with `bundle config set --local git.allow_insecure true`, or switch to the `https` protocol to keep your data secure.
