Angular: Add moduleResolution: bundler to tsconfig

[valentinpalkovic]

Closes #34070

What I did

Storybook crashes as soon as TypeScript errors occur in Storybook files. One of the biggest issues currently is that type declarations from Storybook packages require a specific user tsconfig (moduleResolution=bundler). A misconfigured tsconfig file leads to a crash. This PR adds moduleResolution: bundler to the created .storybook/tsconfig.json file, so that types from Storybook packages are detected properly.

6-7: Please add regression coverage for this generated config.

This fixes a template-level crash path, so a fixture/snapshot assertion that generated .storybook/tsconfig.json includes "moduleResolution": "bundler" would help keep it from regressing silently.
