[Fix #6382] Fix Layout/IndentationWidth with Layout/EndAlignment …

[dischorde]

Fixes #6382 to allow:

variable =
  if true
    :foo
  else
    :bar
  end

which currently violates Layout/IndentationWidth & Layout/ElseAlignment when Layout/EndAlignment is set to start_of_line.

I'm okay with this fix. I just cut a new release, so you'll need to rebase on latest master and fix the conflicts in CHANGELOG.

Thanks for your contribution @dischorde! 🙇
