enum : swagger editor automatically adds single quotes to enum string value "Y"

[KurtCoppens]

An example :
- name: periodUnit
in: query
description: The requested rate period unit
required: true
type: string
enum:
- Y
- M
- D
- W
Swagger editor converts Y to 'Y' after saving the file :
- name: periodUnit
in: query
description: The requested rate period unit
required: true
type: string
enum:
- 'Y'
- M
- D
- W

Some YAML parsers treat the strings y Y n N yes no on off (and some others) as boolean values. Adding quotes around Y enforces the string type and will help avoid parsing issues in other OpenAPI-related tools.
