runtime(doc): small updates to the documentation for varargs

- update and correct the documentation for varargs for Vim9 and make
  sure to mention that a <list> type is required.
- mention that 3match is used the matchparen plugin before 9.0.2054
  (actually this is not correct, but before that patch, Vim used the
  hardcoded id 3)

closes: #13403
closes: #13409
