routes became case-sensitive after updating from 23.3.6 to 23.4.0

[cmgchess]

Expected Behavior / New Feature

I expected the route to hit

Actual Behavior / Motivation for New Feature

Route didn't hit. Got 400 error .

Steps to Reproduce the Problem

1. Updated Ocelot and Ocelot.Cache.CacheManager from 23.3.6 to 23.4.0
2. I called this from my frontend. Notice the uppercase letters of the request issued.

getEntityRecords(id: number): Observable<EventLogData[]> {
  const url = 'https://blablabla.azurecontainerapps.io/Entities/${id}/Events/RecordsData';
  return this.httpClient.get<EventLogData[]>(url);
}

ocelot.json looks like this

{
  "Routes": [
    {
      "DownstreamPathTemplate": "/api/entities/{id}/events/recordsdata",
      "DownstreamScheme": "https",
      "DownstreamHostAndPorts": [
        {
          "Host": "blabla-service.net",
          "Port": 443
        }
      ],
      "UpstreamPathTemplate": "/entities/{id}/events/recordsdata",
      "UpstreamHttpMethod": [
        "GET"
      ],
      "FileCacheOptions": {
        "TtlSeconds": 0,
        "Region": "UserCache"
      },
      "RouteClaimsRequirement": {
        "Claims": "ReadEntities"
      }
    }
  ],
  "GlobalConfiguration": {
    "BaseUrl": "https://blablabla.azurecontainerapps.io"
  }
}

3. What's interesting is when I send the request const url = 'https://blablabla.azurecontainerapps.io/entities/${id}/events/recordsdata'; i.e same case as defined in ocelot it worked. The docs mention that it is case-insensitive by default. Is this expected behavior in 23.4.0 or have i missed something.
