[Task]: [Development improvement] Cannot assign multiple values to the autocompleteDataType

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

Currently we cannot assign multiple autocomplete values to `autocompleteDataType`. This property is present under `Property Validation Configuration -> expected`. Due to this we cannot provide auto complete suggestions for scenario were the expected type has two data types.

For example:

```JS
validation: {
type: ValidationTypes.FUNCTION,
params: {
fn: defaultOptionValidation,
expected: {
type: `string | number`,
example: `abc | {{1}}`,
autocompleteDataType: AutocompleteDataType.STRING,
},
},
},
```

### Steps To Reproduce

Current behaviour example:
```JS
validation: {
type: ValidationTypes.FUNCTION,
params: {
fn: defaultSelectedValuesValidation,
expected: {
type: "String or Array",
example: `apple | ["apple", "orange"]`,
autocompleteDataType: AutocompleteDataType.STRING,
},
},
},
```

expected behaviour example:
```JS
validation: {
type: ValidationTypes.FUNCTION,
params: {
fn: defaultSelectedValuesValidation,
expected: {
type: "String or Number",
example: `apple | 123`,
autocompleteDataType: [AutocompleteDataType.STRING, AutocompleteDataType.NUMBER],
},
},
},
```

### Environment

Production

### Version

Cloud

Search the codebase for `autocompleteDataType`, `AutocompleteDataType`, and the Property Validation Configuration `expected` handling. Reproduce the examples with string/number and string/array combinations, then verify that autocomplete suggestions support multiple declared data types and add or update the relevant tests.
