Update project creation in CI

[bitsandfoxes]

Description

Currently, the SDK is using the create-project.ps1 script to create a new, empty project.

This is part of the main CI:

sentry-unity/.github/workflows/ci.yml

Lines 83 to 93 in f770e6c

	smoke-test-create:
	name: Create ${{ matrix.unity-version }} Smoke Test Project
	if: ${{ !startsWith(github.ref, 'refs/heads/release/') }}
	secrets: inherit
	strategy:
	fail-fast: false
	matrix:
	unity-version: ["2019", "2022", "6000"]
	uses: ./.github/workflows/smoke-test-create.yml
	with:
	unity-version: ${{ matrix.unity-version }}

calling into

sentry-unity/.github/workflows/smoke-test-create.yml

Line 40 in f770e6c

run: ./test/Scripts.Integration.Test/create-project.ps1 -UnityPath "${{ env.UNITY_PATH }}"

This is followed by building the project which contains a few steps for downloading, installing, setting up.

sentry-unity/.github/workflows/ci.yml

Lines 162 to 178 in f770e6c

	- name: Download UPM package
	uses: vaind/download-artifact@e7141b6a94ef28aa3d828b52830cfa1f406a1848 # v4-with-wait-timeout
	with:
	name: ${{ github.sha }}
	wait-timeout: 3600
	- name: Extract UPM package
	run: ./test/Scripts.Integration.Test/extract-package.ps1
	- name: Add Sentry to the project
	run: ./test/Scripts.Integration.Test/add-sentry.ps1 -UnityPath "${{ env.UNITY_PATH }}"
	- name: Configure Sentry
	run: ./test/Scripts.Integration.Test/configure-sentry.ps1 -UnityPath "${{ env.UNITY_PATH }}" -Platform ${{ matrix.build_platform }} -CheckSymbols
	- name: Build Project
	run: ./test/Scripts.Integration.Test/build-project.ps1 -UnityPath "${{ env.UNITY_PATH }}" -Platform ${{ matrix.build_platform }} -CheckSymbols:$${{ matrix.check_symbols }} -UnityVersion "${{ matrix.unity-version }}"

Starting with Unity 2021 and newer, Unity provides command line arguments to make this happen during project creation.
