Type signature for Ruby (rbs) allow type checkers (e.g. steep) to statically check for issues in a code base. Developpers must sometimes provide hints when initializing a data structure (e.g. an empty Array) so that the type checker can properly check its usage. These hints are passed with an in-line comment like so: ``` results = [] #: Array[Integer] ``` Rubocop added support for such comments as on option in its Layout/LeadingEmptyLines check in version 1.67.0. This gem currently use a newer version so this option is available but not enabled yet. Enable this option to make it possible to use both rbs and standard at the same time.

This PR add support for RBS in-line annotations.
It replaces #656 which did that but also updated rubocop and had unrelated
changes. Rubocop was updated to a compatible version with #659, so we just
have to turn on the corresponding option of the rubocop check.
