Subject: [PATCH] fix(cli): remove BetterAuthOptions generic type from
 better-auth templates

Prior to this commit, any plugins added to the betterauth setup would
not have inference and would just break builds. This commit removes the
generic type and fixes betterauth's plugins/extensions inferences.
