Description section of pip config is ill-formatted

[deveshks]

The section of docs for pip config Description is not well formatted. There is supposed to be a sublist under the subcommands section and rendered as per

pip/src/pip/_internal/commands/configuration.py

Lines 21 to 36 in 9a91f45

	class ConfigurationCommand(Command):
	"""Manage local and global configuration.
	Subcommands:
	list: List the active configuration (or from the file specified)
	edit: Edit the configuration file in an editor
	get: Get the value associated with name
	set: Set the name=value
	unset: Unset the value associated with name
	If none of --user, --global and --site are passed, a virtual
	environment configuration file is used if one is active and the file
	exists. Otherwise, all modifications happen on the to the user file by
	default.
	"""

But in the docs, all the options end up in a single paragraph
