CodeMod: dynamic-init-list-ctor

Summary:
CodeMod: `dynamic-init-list-ctor`.

The `folly::dynamic::dynamic(std::initializer_list<folly::dynamic>)` constructor is deprecated because its meaning is ambiguous and variable across compilers and compiler versions.

This diff codemods uses of that constructor to use `folly::dynamic::array<...>(...)` instead.

This codemod may not get 100%, but that's okay. Any amount helps.
