"Temperature" is a parameter in OpenAI GPT models, to control for
randomess in the generated content. To decrease the probability of
either escaping the markdown blocks and creating invalid code, we
decreased temperature for all Non-Prose files. For Markdown or Plain
Text, in which more creativity may be a good thing, we increase the
temperature to allow for more randomness. Along with this, we ask the
generate inline prompt to include only the code and not markdown blocks,
as it appears that lower temperature may decrease the probability of
introducing random markdown blocks.

Release Notes (Internal Only):
- Decrease temperature for inline assist on code content.
