Issue:
Custom indexes has no strings, php detects constant.
<!-- PLEASE COMPLETE THIS TEMPLATE -->

- Laravel Version: 8.x (latest)
- PHP Version: 7.4.13
- Blueprint Version: 1.19
- Platform: Mac | Windows | Linux

### Issue:
When generating custom indexes the index will be printed without `''` which causes it to fail on the migrations.

```
Schema::disableForeignKeyConstraints();
     17▕
     18▕         Schema::create('cooltable', function (Blueprint $table) {
     19▕             $table->id();
  ➜  20▕             $table->foreignId('coolcool')->constrained()->cascadeOnDelete()->index(custom_index_coolcool);
     21▕             $table->foreignId('foobar')->constrained()->cascadeOnDelete()->index(custom_index_foobar);
     22▕         });
```

### draft.yaml:
```yaml
# PLEASE PASTE THE DRAFT FILE WHICH REPRODUCES THE ISSUE HERE...
```
Draft is not required, a custom index will fail because it misses strings, therefore php detects is as a constant which is not defined. 

Pull request description:
fix: sanitize modifier attributes
I used this`draft.yml` file.
```yaml
models:
   cooltable:
      coolcool: id foreign:coolcool.id index:custom_index_coolcool
      foobar: id foreign:foobars.id index:custom_index_foobar
```

reverse-engineered from the generated code on #402

```php
Schema::create('cooltable', function (Blueprint $table) {
     19▕             $table->id();
  ➜  20▕             $table->foreignId('coolcool')->constrained()->cascadeOnDelete()->index(custom_index_coolcool);
     21▕             $table->foreignId('foobar')->constrained()->cascadeOnDelete()->index(custom_index_foobar);
     22▕         });
```
Closes #402
