Swagger not encoding multiple key string values

Assemblies affected
ASP.NET Core OData 8.0.11

Describe the bug
Swagger doesn't encode string values in quotes on entity query by key with multiple key properties.
Thus exception is raised :
Microsoft.OData.ODataException: 'The key value (XXX) from request is not valid. The key value should be format of type 'Edm.String'.'

Reproduce steps

• Clone the repo, launch the ODataRoutingSample project from the solution.
• Go to GET /People(FirstName={keyFirstName},LastName={keyLastName})
• Fill in keyFirstName and keyLastName
• Send the HTTP request

Expected behavior
Swagger request works.
