parameter types missed for package-scoped annotations

🐛 Bug

Given the parameter block:

from datetime import (time, date, datetime)
import datetime

dateannotation: datetime.date = datetime.date.today()
datetimeannotation: datetime.datetime = datetime.datetime.now()
timeannotation: datetime.time = datetime.time(12, 30)
datealias: date = datetime.date.today()
datetimealias: datetime = datetime.datetime.now()
timealias: time = datetime.time(12, 30)
datecomment = datetime.date.today()       # type: datetime.date
datetimecomment = datetime.datetime.now() # type: datetime.datetime
timecomment = datetime.time(12, 30)       # type: datetime.time

The parameters identified by papermill --help-notebook notebook.ipynb:

Parameters inferred for notebook 'notebook.ipynb':
  datealias: date (default datetime.date.today())
  datetimealias: datetime (default datetime.datetime.now())
  timealias: time (default datetime.time(12, 30))
  datecomment: datetime.date (default datetime.date.today())
  datetimecomment: datetime.datetime (default datetime.datetime.now())
  timecomment: datetime.time (default datetime.time(12, 30))

The annotations like datetime.date are not recognized, likely because they are not matched by:

papermill/papermill/translators.py

Lines 144 to 147 in 0ee530d

	# Pattern to capture parameters within cell input
	PARAMETER_PATTERN = re.compile(
	r"^(?P<target>\w[\w_]*)\s*(:\s*[\"']?(?P<annotation>\w[\w_\[\],\s]*)[\"']?\s*)?=\s*(?P<value>.*?)(\s*#\s*(type:\s*(?P<type_comment>[^\s]*)\s*)?(?P<help>.*))?$"
	)

Similar to #695 / #806, which report other cases where the regular expression does not identify types.
