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.

使用 npm run build 和 schematics .:ui-generator --name=hello 重现内联 <% ... %> schematic 模板中的空行。首先追踪 Angular CLI schematics 如何渲染模板命令，然后验证生成的输出会省略仅属于命令的空白，同时保留周围的内容。
