Display authentication type valid values

[mooreds]

Previously we were only showing the authenticationType valid values on the token claims page, but it is used in other places:

• login webhooks
• login validation lambda response

This PR does a few things:

• reworks the token claims page to use the AvailableSince component for more consistent styling
• add the authenticationType values to the missing areas mentioned above
• changes the authenticationType include file to be better named (no more underscores!)
• modifies the authenticationType include to take a show_since value, because as types and features are added, displaying availableSince doesn't make sense if the authentiationType was added before the feature was.

eslint fails because it is trying to operate on a file I removed. still trying to figure out how to get gh cli to exclude such files.

I fixed the eslint issues and used javascript since this is a js repo

I thought this was a markdown repo @lyleschemmerling :)
