Implement clear errors or sanitize requests with > or < in the playlist title.

This is related to a problem.
Using > and < in playlists will cause it to error with 400 Bad Request.
Originally found in linsomniac/spotify_to_ytmusic#93
I could not find other characters affected by this. The error it returns does not make perfect sense either.

To reproduce:

.create_playlist(title="this > won't work", description="")
# Server returned HTTP 400: Bad Request.

This is what is returned:

{
  "error": {
    "code": 400,
    "message": "Sorry, something went wrong.",
    "errors": [
      {
        "message": "Sorry, something went wrong.",
        "domain": "global",
        "reason": "badRequest"
      }
    ],
    "status": "INVALID_ARGUMENT"
  }
}

Describe the solution you'd like

Might help to sanitize the request or return a more concise error. It's difficult to determine that it's related to this.

Funny enough, this doesn't work on the Web either. Neither do they have a good error message for it. Not sure it's the task of this project to figure something out that YouTube's not doing

I'd prefer to raise in that case. Not sure if this is just a temporary issue.

PR welcome

Cool, it would help to return the response object within your YTMusicServerError and other exception classes. I'm guessing the INVALID_ARGUMENT status is probably related to this, so it'd be better to check it against that.

Otherwise, would this be an appropriate change to make?

def create_playlist():
        #...
        try:
            response = self._send_request(endpoint, body)

        except YTMusicServerError as error:
            if ("400" in error): # Checks if it's 400 [Bad Request]
                """
                Implemented to counter an undocumented error with no proper response
                Refers to issue https://github.com/sigma67/ytmusicapi/issues/642
                """
                invalid_characters = self._check_has_invalid_playlist_title_characters( title )
                if (invalid_characters): raise YTMusicServerError(error + f"Invalid characters in playlist title: {", ".join(invalid_characters)}")
            
            raise error

def _check_has_invalid_playlist_title_characters(self, title: str) -> list:
        """
        Checks if the playlist title has characters that youtube does not like.

        :param title: Playlist title
        :return: Boolean if playlist title has valid characters or not
        """
        invalid_characters = [">", "<"]
        found_invalid_characters = [char for char in title if char in invalid_characters]
        return found_invalid_characters

Silly me, I closed the issue.
