"has_2FA" defaults to "false" when missing from API response

[rmaalouf]

What happened

Supplying a bot token xoxb- has the side effect that "has_2fa" is not included in the response from Slack's users.list API. Though this is not documented, it has been confirmed by slack support

has_2fa parameter only shows if the person calling that endpoint is an Admin or Owner, and using a user token(starting with xoxp), and not a bot token(starting with xoxb).

In cases where has_2fa is missing from the response, GetUsersContext returns false for all users even though it may be enabled for some.

Expected behavior

has_2fa shouldn't default to false

Steps to reproduce

Configure the SDK with a bot token with the users:read scope. GetUsersContext will default to false for has_2fa.

Versions

I can confirm that I see the same behavior when querying the Slack API. The easiest fix would be to follow what the go-github community SDK follows and use pointers with omitempty for all JSON tags of response bodies.
