Documentation updates on various topics

[hikalkan]

I've planned a cumulative documentation update and writing here as a todo list;

• Databases collection of AbpDbConnectionOptions
• DBMS configuration (like options.UseSqlServer()) can be explained in the EF Core main document too.
• Data annotation validation localization for Mvc / Blazor UI (especially regex and custom attributes)
• Update here since now all modules have ETOs.
• How to override a repository, in the customization document
• DI multiple service registration & resolution
• https://docs.abp.io/en/abp/4.3/Entity-Framework-Core-Other-DBMS (we have -dbms option, but didn't mention it here)
• How to query from dbcontext and use UOW in integration tests (we can also add some example to the startup template)

Just checking on this "Update here since now all modules have ETOs."

This feature is on the road map and will be available in a short term (follow this issue). Once it is implemented, you will be able to subscribe to individual entity types.

I just tried the 4.4-rc1 version and cant find IdentityUserEto anywhere. Will it not be included/published?
