test: force install of peer deps on nestjs test app

[bizob2828]

Description

I noticed nestjs versioned tests started failing on an older version 10.4.9:

Error: Command failed: npx nest build
  src/app.controller.ts:1:38 - error TS2307: Cannot find module '@nestjs/common' or its corresponding type declarations.

  1 import { Controller, Get, Req } from '@nestjs/common';
                                         ~~~~~~~~~~~~~~~~
  src/app.module.ts:1:24 - error TS2307: Cannot find module '@nestjs/common' or its corresponding type declarations.

  1 import { Module } from '@nestjs/common';
                           ~~~~~~~~~~~~~~~~
  src/app.service.ts:1:28 - error TS2307: Cannot find module '@nestjs/common' or its corresponding type declarations.

  1 import { Injectable } from '@nestjs/common';
                               ~~~~~~~~~~~~~~~~
  src/main.ts:1:29 - error TS2307: Cannot find module '@nestjs/core' or its corresponding type declarations.

  1 import { NestFactory } from '@nestjs/core';
                                ~~~~~~~~~~~~~~

  }

Digging more into it, it was because of an peer dep conflict:

npm error code ERESOLVE

npm error Fix the upstream dependency conflict, or retry

This PR updates the setup of test-app by skipping install in nest cli and running npm install manually and forcing peer dep resolution
