chore: bring in missing EE helm chart change [ci skip]

[dannysauer]

Description

This change was initially made in determined-ai/determined-ee@df500801e44a
PR: determined-ai/determined-ee#1121
CC: @carolinaecalderon

I did add documentation in the values file, which was originally missing in EE. Not sure why this parameter is capitalized, since it probably shouldn't be, but cleaning up the helm chart to make it consistent is not within the scope of this PR.

Test Plan

N/A - this'll totally just work (since it's been fine in EE for a while). So confident, I'm skipping CI.

I did run

helm template --set maxSlotsPerPod=2 ./helm/charts/determined/

and validated that there are no parse issues. And then...

sauer@host$ helm template --set maxSlotsPerPod=2 --set oidc.GroupsClaimName=hello --set oidc.enabled=true --set enterpriseEdition=true --set oidc.provider=xxx --set oidc.idpRecipientUrl=xxx --set oidc.idpSsoUrl=xxx --set oidc.clientId=xxx --set oidc.clientSecretName=xxx --set oidc.clientSecretKey=xxx ./helm/charts/determined/ | grep hello

      groups_claim_name: hello

and validated that the parameter works.
