Layout/SpaceAroundOperators should allow literal rationals without spaces

[eki]

Example code:

1/2r + 3

Rubocop 0.77.0 says this:

lib/rational.rb:1:2: C: Layout/SpaceAroundOperators: Surrounding space missing for operator /.
1/2r + 3
 ^ 

Ruby style guide linked by Rubocop says it is preferred not to have spaces around the / in a rational literal: https://rubystyle.guide/#spaces-operators

---

Expected behavior

Rubocop should enforce the Ruby style guide with respect to rational literals. We should prefer 1/2r to 1 / 2r.

Actual behavior

Rubocop prefers 1 / 2r over the recommended 1/2r.

Steps to reproduce the problem

Add a rational literal without spaces around / to some code, run rubocop.
