feat!: cleanup custom logging

[chingor13]

This changes the logger option provided to reviewPullRequest() and createPullRequest() to be a custom Logger interface that code-suggester declares:

interface LogFn {
  /* eslint-disable @typescript-eslint/no-explicit-any */
  <T extends object>(obj: T, msg?: string, ...args: any[]): void;
  (msg: string, ...args: any[]): void;
  /* eslint-enable @typescript-eslint/no-explicit-any */
}

export interface Logger {
  error: LogFn;
  warn: LogFn;
  info: LogFn;
  debug: LogFn;
  trace: LogFn;
}

• This logger interface can be fulfilled by a default Pino logger as well as plain old console.
• We now default the logger to a null implementation to keep output to a minimum while allowing for a custom logger if you want output.
• We can drop the pino dependency as we now provide a null default logger implementation.

Fixes #178
Fixes #183
