Redundant safe navigation
Reports the use of the safe navigation operator (&.) with a non-nil receiver, which can be omitted.
Use the Ignored receivers list to specify method calls used as receivers that should be ignored (for example, Foo#call or Foo::call for an instance or a singleton method respectively).
Example:
value = 1
if value&.even?
# ...
end
