Enable Style/MutableConstant's Recursive option

RuboCop 1.88 added a `Recursive` option to `Style/MutableConstant`, which
extends the cop from freezing the constant itself to freezing the mutable
literals nested inside it, so `[{ a: [] }]` has to be written
`[{ a: [].freeze }.freeze].freeze` rather than only the outer array.

Grape already treats constants and settings as deep-frozen — that is what
`Grape::Util::DeepFreeze` exists for — so the option matches the posture
the codebase already holds itself to, and keeps a nested literal from
being left mutable in new code.

No existing constant is affected: `lib` and `spec` report no offenses
with the option on.
