SAML2 : Allow to put a name for the IDP

### Problem Statement

Hello everyone,

I saw that there were already quite a few options for configuring SSO.
I've been able to configure the SAML2 provider to use DUO but I can't find the option to rename the provider in Sentry to reflect the provider's real name and I end up with the following login link:


Do you think it would be a good idea to add the option to configure the name?
Otherwise, I can implement the DUO provider (In my opinion, this will be like the Azure one, almost a clone of SAML2) because we might not be the only company using DUO for SSO.

Thanks in advance!
