Updates without upgrades

[ebrett]

This will require a hard reset of main (so may want to reconsider), but this branch includes all the functional changes done prior to the switch to Azure but without the javascript and ruby gem upgrades.

• removes unused workflows for GovPAAS
• removes sentry-rails/sentry-ruby which is currently rate limited
• removes cms constraint - only used in GovPAAS
• updates google analytics configuration to use yml file
• updates hotjar id
• removes GovPAAS specific configuration for cloud foundry spaces (subdomain)
• removes credentials for unused rails environments
