Add eduID ACR's to manage

[phavekes]

Add the ACR's supported by eduID to manage, so they can be enforced on the sp-idp configuration

@baszoetekouw is this only config? Does it require changes in other components?

[baszoetekouw]

For production, the changes were made in the ansible repo already: https://gitlab.surf.nl/surfconext/surfconext-deploy-environments/-/merge_requests/352

We still need to modify the defaults in the applications to make this work in the devconf. That means adding he following values:

• "https://eduid.nl/trust/linked-institution"
• "https://eduid.nl/trust/validate-names"
• "https://eduid.nl/trust/validate-names-external"
• "https://eduid.nl/trust/affiliation-student"

to the mfaEntities in https://github.com/OpenConext/OpenConext-manage/blob/main/manage-server/src/main/resources/metadata_configuration/saml20_idp.schema.json
and to the authn_context_levels config in OpenConext-Dashboard's https://github.com/OpenConext/OpenConext-dashboard/blob/main/dashboard-server/src/main/resources/application.properties

@phavekes does the generic MyConext component also use these same (eduid.nl-based) ACCR values?
