fix: compatibility with bundler 4

[doudou]

rubygems_remotes disappeared.

Could you please add an integration test?

[doudou]

There is an install target in the tests. I was considering this problem covered by that test.

[g-arjones]

But it's passing on master, isn't it?

Good point ...

[g-arjones]

It looks like we also have to set BUNDLE_LOCKFILE in BundlerManager#initialize_environment now since Bundler 4 initializes it to .autoproj/Gemfile.lock (which misses user gems)

I probably never hit that line, but autoproj seems to work with our without that change for me (with Ubuntu 24.04)

@doudou Have you tried Bundler 4.0.4+ already?

[g-arjones]

@doudou Are you going to implement the test, or should we merge?

I had to leave all my PRs open so far ... trying to get through the sizeable backlog now.

[g-arjones]

@doudou Do you mind merging this without the tests?

No. Done.
