remove userId as a parameter in Get Questionnaires

[Recelis]

    /// Gets all questionnaires.
    /// </summary>
    /// <returns>A list of QuestionnaireDtos.</returns>
    /// <response code="200">Returns the list of QuestionnaireDtos</response>
    [Authorize]
    [HttpGet("user/{userId:int}")]
    [ProducesResponseType(typeof(IEnumerable<QuestionnaireDto>), StatusCodes.Status200OK)]
    [Produces("application/json")]
    public async Task<ActionResult<IEnumerable<QuestionnaireDto>>> Get(int userId)```

Bearer Token already contains userId so we can remove userId as a parameter in Get Questionnaires.
