@ngx-env not working with `localize` option in SSR

@ngx-env/builder:application does not support the localize key from Angular's default way of doing i18n - https://angular.io/guide/i18n-common-merge#generate-application-variants-for-each-locale - when using SSR.

If localize is set to anything other than false, then ng build will fail with the following error:

❌ Failed to replace variables in path\to\project\ngx-env-localize\dist\ngx-env-localize\server\index.server.html ❌
Error: ENOENT: no such file or directory, open 'path\to\project\ngx-env-localize\dist\ngx-env-localize\server\index.server.html'

  syscall: 'open',
  path: 'path\\to\\project\\ngx-env-localize\\dist\\ngx-env-localize\\server\\index.server.html'
}

The issue is easy to spot in the source files:

https://github.com/chihab/dotenv-run/blob/a614db48e37c730dc3bd72979a17f250d406078f/packages/angular/src/builders/utils/esbuild-index-html.ts#L28C1-L30C6

The outputDir references dist/project-name & then the path to the index.server.html file is hard coded, whereas localize dynamically adds all the locales defined in it (e.g.: en), so the full path looks like this: dist/project-name/server/en/index.server.html

Reproduction

Here's a repo reproducing the issue: https://github.com/yonguelink/ngx-env-localize-issue-reproduction

The issue can also be reproduced without any source by doing the following:

Create the project & add the features

ng new --ssr ngx-env-localize
cd ngx-env-localize
ng add @angular/localize
ng add @ngx-env/builder

Configure the localization minimally in angular.json

ng config projects.ngx-env-localize.i18n.sourceLocale en
ng config projects.ngx-env-localize.architect.build.options.localize true

Try to build with ng build
