`outletGSId` becomes `outletGsId` through camel case

`outletGSId` becomes `outletGsId` through camel case function, when in theory I would expect it to do nothing with the value 🤔 Am I missing something here?

Here are the test-case I am running:

```
"change-case": "^5.4.4",
```

```
import {
camelCase
} from 'change-case';
describe('camelCase', () => {
test('should not change outletGSId', () => {
const content = camelCase('outletGSId');
expect(content).toEqual('outletGSId');
});
});
```

Start at the camelCase entry point and trace how the supplied `outletGSId` value is split and recombined. Run the provided test case and compare its result with the expected unchanged value; done means the regression is covered and the test passes without breaking other camel-case behavior.
