What is the current behavior?

Currently, the prettier block in package.json does not fully align with Angular’s recommended defaults as defined in .editorconfig.
This can lead to inconsistent formatting across projects, as common preferences like "singleQuote": true and "printWidth": 100 are not enforced in Prettier, even though .editorconfig specifies similar rules.

Issue Number: #30744

What is the new behavior?

The prettier block in package.json has been updated to include Angular’s recommended defaults (singleQuote: true, printWidth: 100), ensuring consistency between .editorconfig and Prettier formatting across all projects.
