Describe the bug / provide steps to reproduce it

I have seen some issues talking about snippets and indentation, but they are edge cases where spaces and tabs are working, but the line after the snippet doesn't indent or something similar, not about or \t not working out the box.

When running a snippet, spaces and/or tabs are not output. For example the below snippet:

{
    "PHPUnit Class": {
        "prefix": "ptest",
        "body": [
            "<?php",
            "",
            "declare(strict_types=1);",
            "",
            "namespace Tests$2;",
            "",
            "use Tests\\TestCase;",
            "use Tests\\Traits\\ShouldNotUseDatabase;",
            "",
            "class $1Test extends TestCase",
            "{",
            "\tuse ShouldNotUseDatabase;",
            "",
            "\tpublic function test$3(): void",
            "\t{",
            "\t\t$0",
            "\t}",
            "}"
        ],
        "description": "Skeleton for a PHP Unit class"
    }
}

Produces the below PHP code where there is no indentation at all.

<?php

declare(strict_types=1);

namespace Tests;

use Tests\TestCase;
use Tests\Traits\ShouldNotUseDatabase;

class Test extends TestCase
{
use ShouldNotUseDatabase;

public function test(): void
{

}
}

Another nice to have would be that the snippet adheres to the tab stop that it was run on. Every time I run a snippet when tabed in it will remove any indentation and put the snippet against the left side.

just here to add another example:

{
  "dependency block": {
    "prefix": "dependency ",
    "body": [
      "dependency \"${1:name}\" {",
      "  config_path                             = \"${2:path}\"",
      "  mock_outputs_allowed_terraform_commands = [\"validate\"]",
      "  mock_outputs = {",
      "    ${3:key} = \"${4:value}\",",
      "  }",
      "}",
      "${0}"
    ],
    "description": "Add a dependency block"
  }
}

and this is what comes out:

dependency "name" {
  config_path                             = "path"
  mock_outputs_allowed_terraform_commands = ["validate"]
mock_outputs = {
  key = "value",
}
}

I tried to figure out the pattern on when indentation is respected and when not, but I couldn't discern anything 🤷🏻

I ran into this when trying to add snippets to the Ruby extension.
