Mustermann warnings on load

[mglenn]

Mustermann 2.0 was released yesterday (July 18th, 2022). Grape relies on mustermann-grape which relies on mustermann specified as mustermann (>= 1.0.0), hence the jump to 2.0.

Getting the warning
lib/ruby/gems/2.7.0/gems/mustermann-2.0.0/lib/mustermann/ast/translator.rb:76: warning: Skipping set of ruby2_keywords flag for translate (method accepts keywords or method does not accept argument splat)

I assume it's in reference to stack.rb at

grape/lib/grape/middleware/stack.rb

Line 69 in f5d9831

ruby2_keywords :insert if respond_to?(:ruby2_keywords, true)

but I'm not certain what the issue is or how to correct it.
