Update procedure to install Firefox in Node/Standalone Firefox

[VietND96]

This update doesn't affect the usual user. This might impact advanced users who rely on official Docker images to customize, build multi-stage, or upgrade the Firefox version by themselves.

Before, via Dockerfile to build Node Firefox, you might see that Firefox is installed by downloaded package .tar.bz2, extract to /opt/firefox and create a symlink /usr/bin/firefox for the executable.

Now, we switch to install Firefox from deb package through the APT (following Firefox instruction).

For the latest version of Firefox stable, beta, devedition, esr, nightly. We install it through APT repo https://packages.mozilla.org/apt.
For an input version, we download the deb package from https://download-installer.cdn.mozilla.net/pub/firefox/releases/ and install it through APT also.

The benefit could see

• Via package manager, any dependencies needed for Firefox are installed together.
• After installing Firefox, through APT we can do one more update & upgrade all dependencies for patching CVEs. A scan results for Node Firefox image with old and new installation approaches.
