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.

Reproduisez les lignes vides du modèle schematic inline <% ... %> à l’aide de npm run build et de schematics .:ui-generator --name=hello. Commencez par retracer la manière dont Angular CLI schematics effectue le rendu des commandes de modèle, puis vérifiez que la sortie générée omet les espaces blancs propres aux commandes tout en préservant le contenu environnant.
