[Linux/Ubuntu] Read snap YAML files to get browser version and executable path

[roniemartinez]

What?

Read browser information from snap YAML files instead of reading .desktop files from /var/lib/snapd/desktop/applications.

browsers/browsers/linux.py

Line 27 in 9a26f1e

"/var/lib/snapd/desktop/applications",

Why?

Specification: https://snapcraft.io/docs/snap-format

The snap format contains the browser version and executable path so there is no need to execute browser --version to get/parse the actual browser version.
