AbpDefaultTenantStoreOptions cannot bind tenant connenctionStrings from appsettings.json,

[fenggaoyao]

AbpDefaultTenantStoreOptions fill tenants from appsettings.json,"Id","Name" can work well ,but cannot get ConnectionStrings. “ConnectionStrings” property only has “get” method
If add public ConnectionStrings ConnectionStrings { get; set; } ,it work well
in this “ConnectionStrings” property can add "set" method ?

original code
https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.MultiTenancy/Volo/Abp/MultiTenancy/TenantConfiguration.cs
` public class TenantConfiguration
{
public Guid Id { get; set; }

    public string Name { get; set; }

    public ConnectionStrings ConnectionStrings { get; }`

the appsettings.json
"Tenants": [ { "Id": "446a5211-3d72-4339-9adc-845151f8ada0", "Name": "tenant1", "ConnectionStrings": { "Default": "...write tenant1's db connection string here..." } }, { "Id": "25388015-ef1c-4355-9c18-f6b6ddbaf89d", "Name": "tenant2", "ConnectionStrings": { "Default": "...write tenant2's db connection string here..." } }
