Layout/HashAlignment: Allow both key and table styles

[root-expert]

In the latest modulesync rubocop was auto-correcting:

{
   "foo"    => "bar",
   "forbar" => "bar"
}

to

{
   "foo" => "bar",
   "forbar" => "bar"
}

Generally in the puppet world we are used to align to the => and a lot of specs are written this way (and I think it's better to stay this way)

is that the old or the new style?

[root-expert]

The new, rubocop is currently auto-correcting to:

{
   "foo" => "bar",
   "forbar" => "bar"
}

I do agree we need something for this because it's making huge changes in some modules for (IMHO) no benefit. I'd like a consistent style, whether it's the old or new. Just as long as it doesn't mix styles. Reading https://www.rubydoc.info/gems/rubocop/0.83.0/RuboCop/Cop/Layout/HashAlignment it said:

Alternatively you can specify multiple allowed styles. That's done by passing a list of styles to EnforcedStyles.

Do we have a module where we can test if this works?

[root-expert]

Sorry, I completely forgot about this PR. I added so both key and table styles are allowed. I think that's the most used styles. separator seems a little bit weird.

I will test this on puppet-example module

Tested here: voxpupuli/puppet-example#21

Thanks!
