make-fontawesome5.py: Fix YAML load warning

Use `yaml.safe_load()` instead of `yaml.load()` to fix the following
warning:

    YAMLLoadWarning: calling yaml.load() without Loader=... is
    deprecated, as the default Loader is unsafe. Please read
    https://msg.pyyaml.org/load for full details.

In addition, add a comment that the 'icons.yml' URL that has the '/raw'
part is actually correct, because we need the raw YAML data instead of
the HTML page rendered by Github.
