fix(bugs): use explicit link targets, and fix punctuation and wording

Both link names in this message are translated. When a message contains
more than one translated reference name, Sphinx's fix-up has to guess
which original target each one means, so it cannot verify the result.
Naming the targets explicitly removes the guess; the rendered links are
unchanged.

While here, fix the last sentence:

* Two commas split the sentence in the wrong places: one between the
  verb 得到 and its object, and one between an attributive and its head
  noun 答案.
* 「Python 修正錯誤」 reverses subject and object. The English is
  "fixing issues *in* Python", so it is 修正 Python 的問題.
* *issues* here are tracker items rather than defects, so 問題 reads
  better than 錯誤.
