Fix TypeError in Fixture creation

Ruby 4.2 started doing `value.gsub('$LABEL', label)` for fixture label interpolation, but you can have have valid YAML where `label` isn't a String. 

For example:

```YAML
0:
  name: John
  email: johndoe@gmail.com
1:
  name: Jane
  email: janedoe@gmail.com
```

This YAML will create a label that is a Fixnum, causing `TypeError: no implicit conversion of Fixnum into String.`
