fix: only exclude forced subs when --forced-subs flag is not set

Previously, forced subtitles were incorrectly included when they matched
languages in the lang configuration, even without the --forced-subs flag.
This caused forced subs to appear when using language configs or the -l
parameter, which violated the expected behavior.
