Description

Fixed a compatibility issue between Storybook and TypeScript 5.x.

Notes

Storybook doesn't play nice with TypeScript 5.x, and we just bumped our TS version. This is affecting the deploy:pages action on GitLab, as well as Storybook itself.

See this closed, unfixed issue on Storybook: storybookjs/storybook#21642

Fix (graciously) taken from here: hipstersmoothie/react-docgen-typescript-plugin#78
