[BUG] options.authnContext as a string is no longer supported

[Mus Radi]

Hi everyone

We have defined the options.authnContext parameter as a string (client configuration) and we are getting an error because the new versions of Passport-SAML are expecting this parameter to be an array only. This is a regression compared to previous versions which support both string and array types.

Expected behavior

The previous versions were creating an array which contains options.authnContext string item.

Environment

• Node.js version: 14
• passport-saml version: 3.2.1

I believe that this was discussed at PR #615 (see especially comment #615 (comment))
