Add support for type mapping in EF Core 10 (MySQL Connector/NET)Add support for string[] type mapping in EF Core 10

[ahmetsevgili]

This PR introduces support for string[] type mapping in the MySQL EF Core provider.
Problem
When using EF Core 10 with MySQL, queries that rely on Contains with a string[] fail with the following exception:

``InvalidOperationException: Expression '@stringarray' in the SQL tree does not have a type mapping assigned.'`

This occurs because the provider does not currently assign a relational type mapping for string collections, even though EF Core 10 expects it.

Solution

The type mapping source has been updated to handle both string and string[]:

else if (clrType == typeof(string) || clrType == typeof(string[]))
{
    // existing string mapping logic
}

This ensures that string[] is recognized and mapped correctly, allowing queries such as:

string[] stringArray = new string[] { "TEST" }; var result = context.StringCodeMatch.FirstOrDefault(q => stringArray.Contains(q.Code));

to execute without error.
