Alloy fmt use "space" instead of "tab" for indentation

[duthifree]

Request

Is it possible to change indentation from "tab" to "space" when i use alloy fmt please ?

Use case

In Kubernetes, when i create ConfigMap from file, \n... are prints instead of a newline. It's hard to edit or consult ConfigMap with this formatting.

Today:

apiVersion: v1
data:
  test.alloy: "test.example \"xxx\" {\n\foo = \"bar\"\n}\n"
kind: ConfigMap
metadata:
  name: alloy
  namespace: grafana-alloy

Expected :

apiVersion: v1
data:
  test.alloy: |
    test.example "xxx" {
      foo = "bar"
    }
kind: ConfigMap
metadata:
  name: alloy
  namespace: grafana-alloy

I think this maybe cause by the terminator is '\n'? maybe it need to add terminator judge for '\t'
