Insert {:axiom} quick fix fails on assume clauses

[masecla22]

Info

I'm working with the Dafny intergration for VSCode (v3.3.1) and I have upgraded to the latest version of Dafny (4.7.0)

Reproducing steps

1. Open VSCode with Dafny Integration enabled
2. Place the following code:

method Main() {
  assume 1+1==2; 
}

3. Wait for assume statement has no {:axiom} annotationVerifier[r_assume_statement_without_axiom](https://dafny.org/dafny/HowToFAQ/Errors#r_assume_statement_without_axiom) warning to show up.
4. Apply "insert {:axiom}" quick-fix
5. Obtain the following code

method Main() {
  {:axiom}assume 1+1==2;
}

Expected behaviour

I would expect the axiom annotation to show up in the intended spot as such:

method Main() {
  assume {:axiom} 1+1==2;
}

Let me know if there is any further information I should add.
