### Godot version

Godot 4.0.1.stable

### System information

### Issue description

Example code:

```gdscript
@warning_ignore("shadowed_global_identifier")
static func print_debug(msg: String):
```

the warning is ignored by pressing [ignore] in the warnings panel.

pressing it multiple times results in:
```gdscript
@warning_ignore("shadowed_global_identifier", "shadowed_global_identifier")
```


### Steps to reproduce

Shadowing a global function with a method of script:

```gdscript
@warning_ignore("shadowed_global_identifier")
static func print_debug(msg: String):
```


### Minimal reproduction project

```gdscript
@warning_ignore("shadowed_global_identifier")
static func print_debug(msg: String):
    pass
```
