Allauth: update to use latest version

[stsewd]

What's the problem this feature will solve?

The latest versions of allauth include some improvements and fixes related to SAML, which is a feature we are active developing for .com.

Last time I saw that were some breaking changes related to templates, and changes around using json fields.

Additional context

The last time we updated allauth (#11134) we hit only one problem I think, it was related to a missing changelog entry about a field change in google. Another problem we had we about the settings, but that wasn't related to allauth itself, but to our settings inheritance.

What are those improvements and fixes? Knowing that will help us to work on prioritization of this upgrade.

You can just check the changelog and look for "SAML" https://docs.allauth.org/en/latest/release-notes/recent.html Some important ones are:

• SAML: accessing the SLS/ACS views using a GET request would result in a crash (500).
• SAML: the login view did not obey the SOCIALACCOUNT_LOGIN_ON_GET = False setting.
