fix: improve ts output for create logger (#8763)

## Description
Typescript =< 5.2 generated better types for `log` than >= 5.3. We're on
5.5 as that has the better import syntax.
Changing createLogger to use `function log()` rather than `const log =
function()` outputs as before.

Also updates typescript to 5.5.1 (rc) from 5.5.0 (beta).

5.2, or 5.5 with this change
```
export default log;
declare const log: {
    (...args: any[]): void;
    createLogger(subName: string, subDelimiter?: string, subStyles?: string): any;
    createNewLogger(newName: string, newDelimiter?: string, newStyles?: string): any;
    levels: any;
    level(lvl?: "info" | "error" | "all" | "debug" | "warn" | "off"): string;
    history: {
        (): any[];
        filter(fname: string): any[];
        clear(): void;
        disable(): void;
        enable(): void;
    };
    error(...args: any[]): any;
    warn(...args: any[]): any;
    debug(...args: any[]): any;
};
export const createLogger: (subName: string, subDelimiter?: string, subStyles?: string) => any;
//# sourceMappingURL=log.d.ts.map%
```

5.3+, without this change
```
export default log;
declare function log(...args: any[]): void;
declare namespace log { }
export const createLogger: (subName: string, subDelimiter?: string, subStyles?: string) => any;
//# sourceMappingURL=log.d.ts.map%
```
