Show [default: boolean] in --help command

[poasungoh]

System.CommandLine v2.0.6 removed the support for showing [default:boolean] in --help command.

If we set our option default value as "True" or "False", it will not be showing when we enter --help.

Example: v2.0.6

Options:
--IsConnected (REQUIRED) Indicate connection need to be connected (boolean).

Expected:

Options:
--IsConnected (REQUIRED) Indicate connection need to be connected (boolean). [Default: True]

In previous version, it will show True if we set default value as True. Or show False, if we set default value as False
