* Skip Spring version 2.1.1
Changes introduced in spring 2.1.1
(https://github.com/rails/spring/pull/621) are breaking some tests. That
change was reverted in https://github.com/rails/spring/pull/629, but
hasn't been released yet. Until #629 is released, this PR skips Spring
version 2.1.1.
* Bump to latest standard to match CI
We are using the latest standard on CI. This bumps the version in the
dev Gemfile to match, and fixes one violation.
