Volto/Plone SAML2 authentication

Hello Plone Community :wave:

This is Vamshi and I am excited to discuss SAML2 support for Volto/Plone. I have completed all the necessary training as mentioned in the documentation and I am confident in my abilities to execute this task, thanks to the clear and concise documentation.

Through my extensive research, I have gained the knowledge required to add-on SAML2 support for Plone. I am confident in my findings and would love to discuss it and draft a proposal for GSOC'24 under the guidance of the mentors
