fix: remove transformedCSS <style> wrap

[nkxrb]

<style${meta}>\n${transformedCSS}\n</style>

This writing breaks the source structure, resulting in generated hash inconsistencies, resulting in incorrect scopeId matching in vue。

so, I remove '\n' in <style${meta}>\n${transformedCSS}\n</style>

[nkxrb]

for example:

<style lang="scss" scoped>.list{color: red}</style>

vue will build three time
scopeId: b7d8492c rawQuery: ''
scopeId: b7d8492c rawQuery: 'vue&type=script&lang=ts&setup=true'
scopeId: b7d8492c rawQuery: 'vue&type=style&index=0&id=b7d8492c&lang=scss&scoped=true'

but installed windicss

windicss will build

<style lang="scss" scoped>\n.list{color: red}\n</style>

scopeId: 3bda2322 rawQuery: ''
scopeId: b7d8492c rawQuery: 'vue&type=script&lang=ts&setup=true'
scopeId: b7d8492c rawQuery: 'vue&type=style&index=0&id=b7d8492c&lang=scss&scoped=true'
