FR: Flag to show TOS and Privacy Policy on SignIn screen

[jzila]

Using https://supertokens.com/docs/thirdpartyemailpassword/common-customizations/signup-form/toc-privacypolicy, you can show your TOS and Privacy Policy on the SignUp screen.

However, ThirdParty login signs you up automatically even if you click the button through the SignIn screen. So such users might never have seen the Privacy Policy/TOS links.

I propose a flag: showPrivacyAndTOSOnSignIn, defaulted to false to show any enabled links on the SignIn screen as well. This flag would only have meaning if either or both of termsOfServiceLink or privacyPolicyLink are enabled.
