Ref and Memo options break rest props typing

[katywings]

🐛 Bug Report

Using svgr with the "--ref" option results in "Property does not exist in ..." typescript errors for rest-spread props:

To Reproduce

• Create a typescript environment (in my case I used codesandbox and locally nextjs)
• Create svg components with svgr --ref
• Make sure that the svg component is imported with types (allowJs enabled in tsconfig)
• (Note: the error happens independent if the --typescript svgr option is set or not

Expected behavior

Rest spreaded props should be possible while using forwardRef

Link to repl or repo (highly encouraged)

• Demo: https://codesandbox.io/s/dreamy-lederberg-7xkwz?file=/src/App.tsx:340-345
• There are two icon components in the demo:
  • Icon: original icon generated by svgr with svgr --ref ...
  • IconFixed: icon after my pr which follows in a few minutes :D

Run npx envinfo --system --binaries --npmPackages @svgr/core,@svgr/cli,@svgr/webpack,@svgr/rollup --markdown --clipboard
