Allow managing 'forms' within authenticationinfo for puppetlabs-iis resources

[aaronhilton0]

Use Case

Currently the iis_site and iis_application resources in the puppetlabs-iis module (10.0.1) support the following options within "authenticationinfo":
['anonymous', 'basic', 'clientCertificateMapping','digest', 'iisClientCertificateMapping', 'windows']
per https://github.com/puppetlabs/puppetlabs-iis/blob/main/lib/puppet_x/puppetlabs/iis/property/authenticationinfo.rb

I have nodes running Windows Server 2022 that have 'Forms Authentication' listed as an option, and I'd like to leverage the existing mechanism in this module to ensure that auth option is disabled instead of resorting to DSC.

Describe the Solution You Would Like

Allow an option to manage 'forms' in the same manner as the other authenticationinfo methods

Describe Alternatives You've Considered

Using DSC could allow this, however it is an undesired method.
