After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

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.
The way ruby loads gems and keeps track of their paths seems to not
always work very well when the gems are accessed through
symlinks. Ruby will then complain that the same files are loaded
multiple times; it relies on the file's full path to determine whether
the file is loaded or not.
This adds an option to simply copy all gem files into the environment
instead, which gets rid of this issue, but may instead result in major
file duplication.
The bin stubs need to be built where there's access to /nix/store - so
it can't happen in a nix-shell run. Ergo, a shell.nix needs to be able
to signal to the build that all bins need to be built.
`usesGemspec` no longer required to trigger the "copy everything into
gemfile-and-lock" behavior. If the mainGem is referred to by path,
that's sufficient.
Add `pname` attribute: if passed, the derivation name defaults to the
gem name + version and only expose the gem's bin.
Add `gemdir` attribute: gives a default lookup path for the Gemfile,
Gemfile.lock and gemset.nix.
Set the `meta.platforms' to `ruby.meta.platforms' by default.
