Add more information about sequential GUID generation

### Type of issue

Missing information

### Description

The section "GUIDs" currently links to the SQL Server's [NEWSEQUENTIALID](https://learn.microsoft.com/en-us/sql/t-sql/functions/newsequentialid-transact-sql) function and says that EF core works "similar". I think this should be clearified.

For example:
- SQL Server's NEWSEQUENTIALID documentation page says "After restarting Windows, the GUID can start again from a lower range". Does EF Core suffer from the same problem?
- What if the app using EF Core is not running on Windows? (Btw, that information is also missing in the SQL Server documentation.)
