SAML nor OpenID_Connect display_name seem to be respected

[samip5]

Steps to reproduce the problem

1. Install Mastadon like you normally would
2. Add SAML or OpenID Connect variables to env, with an DISPLAY_NAME variable
3. Notice that the login page shows just openid_connect or saml rather than what was the variable set to.

Expected behaviour

It should have been set to the attribute value

Actual behaviour

It was using openid_connect or saml respectfully

Detailed description

Despite #18568 being merged, it would need a new release to fix this or manually changing those.

Specifications

Mastadon v3.5.3
Firefox 106.0.1 on Gentoo linux

Can also confirm on a new 3.5.3 install with OIDC configured and working properly that login button only displays "Or log in with OPENID_CONNECT".

Tried using Chrome on Windows, Android, and Ubuntu, Edge on Windows and Android, and Firefox on Windows, Android, and Ubuntu.

As noted in the opening post, #18568 addresses the issue.
