Remove ident from proxies

[johndaley-me]

Identity team is trying to use dtmulator in our apps but since many of our apps have binding_sets such as recovery.identity, by default the requests for our pages are being proxied to the integration app because of the /ident/ proxy entry. Removing the ident proxy entry will resolve this issue.

There still are some usages of this for entering/existing helper mode. We could probably work with those teams to add a proxy entry for those limited cases.

Just brainstorming, here are some alternatives:

• Remove the /ident proxy--search GitHub usage and notify those impacted so they can create a proxy rule
• Provide/figure out a way to opt out of the /ident proxy that Identity team can use or Identity team can work around it with something like require('@fs/react-scripts/proxy/proxies').find(({ route }) => route === '/ident').route = '/ident-no-proxy' in their setupProxy file
