Documentation: Add note on double escaping "\n" being necessary for lmql.run, but not for @lmql.query.

[JasperDekoninck]

In the following query, I am still required to write "\n" instead of "\n" in order to be able to compile the query in the Python package (note that this specific query also fails for other reasons, see #61):

argmax(chatty_openai=True, max_len=256)
   "A rhyme:\\n"
   "Verse: [RHYME_START]\\n"
   for i in range(5):
      "Verse: [RHYME]\\n"
from
   'openai/text-davinci-003'
where
   len(TOKENS(RHYME)) == 5 and len(TOKENS(RHYME_START)) == 5

Are you using lmql.run or LMQL via decorator functions @lmql.query.

[JasperDekoninck]

Aah yes, I am using lmql.run, forgot that the problem cannot be really fixed there. Maybe something to add to the documentation?
