feat: improve sdkmanager install for build tools and platforms

[maiconcarraro]

Context

A new container based on this image is going to have no platforms and outdated version of build-tools, example:

Above red line is the initial files/folders before any request, and below red line is once you request to build a new app, its going to download and install the required versions for the latest bubblewrap. See it has 2 different build tools, the v33 that is installed because of this Dockerfile, and the v34 required for the bubblewrap + platforms during execution time.

Intermittent bug

In PWABuilder there is one intermittent issue causing the request to fail because of Failed to find target with hash string 'android-35' (see)

I don't have context if it's related to an old container running, or if it can be related to a new container failing to download and install, so this PR also includes a possible fix for this.

New result

Again above red line is a new container without request and below is after request.

It should speed up the success rate and performance since it doesn't need to install at execution time for a new container.

I was trying to reproduce the intermittent issue using the existing version (build tools v33) and my approach was trying concurrent requests before it has installed the correct build-tools/platforms, and it corrupted the environment

The chances to happen are low because it needs to be a new container, but this PR will prevent this anyway. Still investigating.
