Writing Your Own Templates section does not work

## Current behaviour 💣

I am trying to use the `templateParameters` to pass some variables into my template and it does not work.
I have followed the examples shown:
- Here: https://github.com/jantimon/html-webpack-plugin#writing-your-own-templates
- And here: https://github.com/jantimon/html-webpack-plugin/tree/main/examples/template-parameters

## Expected behaviour ☀️

I would like my `<%= title %>` to be replaced with the actual value of my `templateParameters.title` value, i.e. value located inside `locales/de-DE.json` or `locales/en-GB.json`.
I've also tried to modify the `<%= title %>` to `<%= htmlWebpackPlugin.options.templateParameters.title %>`.

### Reproduction Example 👾

I have created a small repository to reproduce this issue here: https://github.com/einazare/html-webpack-plugin-18n-generator
You will need to:
1. Install the dependencies with `npm install`
2. Build the application with `npm run build`
3. Open `dist/index.html`
4. You will see `<%= title %>` was not replaced by `Some title written in English (Great Britain)`

## Environment 🖥

All the versions from my `package.json` file here:
```
"dependencies": {
"copy-webpack-plugin": "11.0.0",
"html-webpack-plugin": "5.5.0",
"webpack": "5.88.2",
"webpack-cli": "4.9.2",
"webpack-dev-server": "4.8.1"
},
"devDependencies": {
"css-loader": "6.7.1",
"html-loader": "4.2.0",
"style-loader": "3.3.1"
}
```

Also, the output of the above commands here:
```
node -e "var os=require('os');console.log('Node.js ' + process.version + '\n' + os.platform() + ' ' + os.release())"
Node.js v18.16.0
darwin 22.6.0
```

```
npm --version
9.5.1
```

```
npm ls webpack

Thank you 🙏

Start with the linked reproduction repository, install its dependencies with npm install, and run npm run build. Read package.json and the locale files at locales/de-DE.json and locales/en-GB.json, then inspect the generated dist/index.html. Done means the template renders the expected title instead of the literal <%= title %> text.
