Update RuboCop in Gemfile to silence a deprecation warning in build (#870)

The existing version of RuboCop no longer works against other libraries
without deprecation warnings; rather than lock more dependencies,
upgrade RuboCop used in project.

```sh
Running pre-commit hooks
Check YAML syntax........................................[YamlSyntax] OK

Unexpected output: unable to determine line number or type of error/warning for output:
`EnsureNode#body` is deprecated and will be changed in the next major version of rubocop-ast. Use `EnsureNode#branch` instead to get the body of the `ensure` branch.
