Default moduleResolution to 'bundler' instead of 'node'
The writeConfigurationDefaults function was writing 'node' as the default
moduleResolution value for auto-generated tsconfig.json, while
create-next-app templates already used 'bundler'. This inconsistency meant
that projects set up without create-next-app got the legacy 'node' setting.
Since TypeScript 5.0+ (and Next.js requires >= 5.1) supports 'bundler'
moduleResolution, and Turbopack is the default bundler, 'bundler' is the
correct modern default. Existing projects with 'node' are not affected
since it remains in the parsedValues allow-list.
