jest 27 transformer for storyshot

don't work @storybook/addon-storyshots in Jest version 27 provide unoffitial package for storyshots in Jest v27

npm install -D @eiel/storyshot-jest-27

update jest.config.js for storyshot

 transform: {
-  '^.+\\.stories\\.tsx?$': '@storybook/addon-storyshots/injectFileName',
+  '^.+\\.stories\\.tsx?$': '@eiel/storyshot-jest-27',
   '^.+\\.[jt]sx?$': 'babel-jest',
 },

Jest transformer API break change in Jest v27. see https://jestjs.io/docs/code-transformation Don,t fix still offitial Jest transform by storybook. So, I wrote alternate transformer for storyshot in Jest v27.

I will archive this repository when official support Jest v27 release.
