[Schema Inaccuracy] GET /issues uses escaped markdown

[masklinn]

The filter parameter to GET /issues escapes all the list-items, leading to the markdown-rendering of the description yielding an "ascii" list rather than a proper list for the output format:

Indicates which sorts of issues to return. Can be one of:
* assigned: Issues assigned to you
* created: Issues created by you
* mentioned: Issues mentioning you
* subscribed: Issues you're subscribed to updates for
* all: All issues the authenticated user can see, regardless of participation or creation

Expected

Not escaping the list items, leading to the correct rendering:

Indicates which sorts of issues to return. Can be one of:

• assigned: Issues assigned to you
• created: Issues created by you
• mentioned: Issues mentioning you
• subscribed: Issues you're subscribed to updates for
• all: All issues the authenticated user can see, regardless of participation or creation
