Using .Databases with a misspelled database name changes database name in SMO

This bug was found using dbatools: https://github.com/dataplat/dbatools/issues/8598

There are two ways to select a single database from the list of databases from a Microsoft.SqlServer.Management.Smo.Server object: $server.Databases | Where-Object Name -EQ <dbname> and $server['<dbname>'].

The first one works without problems. But the second one changes the casing of the name from the original one to the one used to query the database.

Here is the code to show that:

Import-Module -Name dbatools

# correct:
$server = [Microsoft.SqlServer.Management.Smo.Server]::new('sql01')
$server.Databases | Where-Object Name -EQ Master | Select-Object -ExpandProperty Name
$server.Databases['Master'] | Select-Object -ExpandProperty Name

# wrong:
$server = [Microsoft.SqlServer.Management.Smo.Server]::new('sql01')
$server.Databases['Master'] | Select-Object -ExpandProperty Name
$server.Databases | Where-Object Name -EQ Master | Select-Object -ExpandProperty Name

And here is a screenshot:

Yes, I'm using not the current version - but I don't have the current version at hand. But I think it will take you only minutes to test this in your test environment. If it is fixed with the current version: Sorry to bother you.

Comienza reproduciendo el comportamiento con los ejemplos de PowerShell usando Server.Databases y su indexador de cadenas. Después, sigue la implementación detrás de la búsqueda en la colección Databases y añade cobertura de regresión para una consulta con una combinación de mayúsculas y minúsculas diferente o con un error ortográfico. Se considera terminado cuando consultar una base de datos ya no cambia el nombre original de la base de datos ni sus mayúsculas y minúsculas.
