fix(core): align create-nx-workspace style options with framework support

[ryanhefner]

Current Behavior

create-nx-workspace offers stylesheet options for React and Next.js that their application generators do not support, including Emotion, styled-components, styled-jsx, and Less.

The intermediate @nx/workspace:preset schema also restricts style to css and scss. This rejects valid framework-specific options—such as Angular's less—before the final application generator runs.

Expected Behavior

React and Next.js workspace prompts only offer their supported options:

• CSS
• SCSS
• None

The Angular prompt offers:

• CSS
• SCSS
• Sass
• Less

The workspace preset treats style as pass-through data and leaves authoritative validation to the selected framework generator.

Regression tests cover the prompt choices, schema validation, and Angular less workspace generation.

Testing

• pnpm nx test create-nx-workspace
• pnpm nx test workspace
• pnpm nx run-many -t build,lint -p create-nx-workspace workspace
• pnpm nx affected -t build,test,lint --base=origin/master
• pnpm nx prepush

Affected e2e-local validation was attempted, but the local registry bootstrap could not run because Docker was unavailable and port 5000 was already occupied by macOS Control Center.
