bundlerEnv: Allow overriding bundler
Prior to this it doesn't seem to be possible to customize the version of
bundler used in a bundlerEnv app. This change allows something like the
following:

```nix
let bundler = pkgs.buildRubyGem rec {
  gemName="bundler";
  name="bundler-2.2.11";
  version="2.2.11";
  source.sha256="1izx6wsjdm6mnbxazgz1z5qbhwrrisbq0np2nmx4ij6lrqjy18jf";
};
in pkgs.bundlerEnv.override { inherit bundler; } {
  name="test";
  gemdir=./.;
}
```

to use bundler 2.2.11 rather than the 2.1.5 default.

# incorporates the basicEnv as a requirement so that its $out is in our path.
# When stubbing the bins for a gem, we should use the gem expression
# directly, which means that basicEnv should somehow make it available.
# Different use cases should use different variations on this file, rather
# than the expression trying to deduce a use case.
# The basicEnv should be put into passthru so that e.g. nix-shell can use it.
