Repodb: Bug: IsDictionaryStringObject() does not work in F#

[MatejMarecek]

Bug Description

When using RepoDB in F#, passing Dictionary<string, Object> as an argument to operations does not work.

I think that root cause of the problem lies in method IsDictionaryStringObject where the dictionary object type is compared like this type == StaticType.IDictionaryStringObject.

Library Version:
1.12.7

Example code

```F#
let user = Dictionary()
patch.FirstName |> Option.iter (fun value -> user.Add("FirstName", value))
patch.LastName |> Option.iter (fun value -> user.Add("LastName", value))

let! updatedRows = connection.UpdateAsync("User", entity = user, where = where)

It seems that Dictionary<string, object> has not been resolved to the IDictionary<string, object>. Do you have the stack trace of the call?

The issue description was updated with the stack trace

[mikependon]

The fix for this will be available on the next release of the Core library.
