(lua-ts-mode--font-lock-settings): fix font-locking for string escapes

Bug: Strings aren't fontified when they have escape sequences in them.

Recipe to reproduce:
In a `lua-ts-mode` buffer, with `treesit-font-lock-level` set to 4 to
include escapes,

    "foo\nbar"

font-locks '\n' but not "foo" or "bar".
