Fix tts.skip_tags's regex to match newlines

The extension_settings.tts.skip_tags setting is meant to skip sending
tags and their content to the TTS API provider. The original regular
expression matched content inside tags with ".*?". Unfortunately,
Javascript's engine does *not* match newlines on the "." without the /s
flag.

The /s flag was added in ES2018. To be more compatible, the regex
has been changed to "[\s\S]+?". This gives similar performance (instead
of using capture groups) and matches all content within a tag, as the
original regex intended.
