feat: Add scopes option to client

[alldoami]

No new added parameters to the function, the user will need to pass in something like this:

func ScopeOptions(c *Client) {
c.OIDCConfig.Scopes = []string{"blah", "blah"}
}

to add new scopes to the client if they don't want the default scopes.

remove this scopes argument and use the clientOptions instead

[alldoami]

I'm trying to understand how this option works. Could you explain how we'd use it?

[jakeyheath]

kind of like this comment: #1082 (comment).

You'd have an Option function that updates the scopes, rather than passing them in.

Looks good!

As an additional item, please at a SetOauthConfigScope function that does what you say in the comments. Place is under the here:

go-misc/oidc_cli/oidc_impl/client/config_options.go

Line 21 in 7de7eb0

var SetOauth2AuthStyle = func(authStyle oauth2.AuthStyle) Option {

under the other option functions. I feel like that is common of enough of an option that others will want to use it.
