Ensure folders exist to allow installation

[fooman]

bin/magento setup:install checks for writeability of a few folders. Syncing just the .htaccess file allows them to be created.

This has been included in release 0.1.3. Thanks for the PR!

Documenting the testing process I used to validate this indeed fixes the issue for posterity's sake:

1. Install codebase on host machine

    composer create-project --ignore-platform-reqs --repository-url=https://repo.magento.com/ \
        magento/project-community-edition m2test 2.3.2
   

2. Start the project environment

    cd m2test
    
    warden env-init m2test
    warden sign-certificate m2test.test
    warden env up -d
    warden sync start
   

3. Launch a shell session and install Magento

    warden shell
   
    ## Run Magento install routine
    bin/magento setup:install \
        --backend-frontname=backend \
        --amqp-host=rabbitmq \
        --amqp-port=5672 \
        --amqp-user=guest \
        --amqp-password=guest \
        --db-host=db \
        --db-name=magento \
        --db-user=magento \
        --db-password=magento \
        --http-cache-hosts=varnish:80 \
        --session-save=redis \
        --session-save-redis-host=redis \
        --session-save-redis-port=6379 \
        --session-save-redis-db=2 \
        --session-save-redis-max-concurrency=20 \
        --cache-backend=redis \
        --cache-backend-redis-server=redis \
        --cache-backend-redis-db=0 \
        --cache-backend-redis-port=6379 \
        --page-cache=redis \
        --page-cache-redis-server=redis \
        --page-cache-redis-db=1 \
        --page-cache-redis-port=6379
   
    ## Generate an admin user
    ADMIN_PASS="$(cat /dev/urandom | base64 | head -n1 | sed 's/[^a-zA-Z0-9]//g' | colrm 17)"
    ADMIN_USER=localadmin
    bin/magento admin:user:create \
        --admin-password="${ADMIN_PASS}" \
        --admin-user="${ADMIN_USER}" \
        --admin-firstname="Local" \
        --admin-lastname="Admin" \
        --admin-email="${ADMIN_USER}@example.com"
    printf "u: %s\np: %s\n" "${ADMIN_USER}" "${ADMIN_PASS}"
