Angular schematics generates blank lines through template

### Command

generate

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

I have ng schematics template `__name@dasherize__.component.html` with content :

> <% for (let row of getComponents().rows) { %>
>

I build it with :

npm run build
schematics .:ui-generator --name=hello

Generated code creates empty lines on place where is put command "<%" in template, see:

>
>
>

Is there anyway these white spaces can be avoided. If we have to do it manually, it might kill the purpose of this code generator tool

### Minimal Reproduction

Write a schematic template code with inline code <% inline code %>. Then build and generate code using commands

npm run build
schematics .:ui-generator --name=hello

We can see generated code is having while spaces wherever inline code is present.

Tái hiện các dòng trống từ schematic template inline <% ... %> bằng npm run build và schematics .:ui-generator --name=hello. Bắt đầu bằng cách truy vết cách Angular CLI schematics render các lệnh template, sau đó xác minh rằng đầu ra được tạo bỏ qua khoảng trắng chỉ thuộc về lệnh trong khi vẫn giữ nguyên nội dung xung quanh.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
