Autofill does not work until both the number and character fields are filled.

Describe the bug
I expect the street name suggestions to appear after entering just a few characters. However, I am not receiving any results until I enter the first number. This behavior is not aligned with the expected functionality.

Environment:
https://docs.mapbox.com/ios/search/guides/address-formfill/

To Reproduce
Steps to reproduce the behavior:

1. Start typing a address by entering only letters
2. See no results are returned

Expected behavior
Suggested addresses should be returned

Smartphone (please complete the following information):

• Device: Any
• OS: Any
• Search SDK Version: 2.9.0
• SearchUI SDK Version: not applicable
• SearchEngine

    private lazy var addressAutofill = AddressAutofill()
    func search(for query: String) {
        guard let addressAutofillQuery = AddressAutofill.Query(value: query) else {
            return
        }

        addressAutofill.suggestions(for: addressAutofillQuery) { [weak self] result in
}

Additional context
When user is typing a number the results are starting to show

Start with the AddressAutofill.Query creation and addressAutofill.suggestions flow shown in the issue, then reproduce the behavior using letters-only input on Search SDK 2.9.0. Done means street or address suggestions appear before a number is entered, while preserving the existing numeric-input behavior.
