Microsoft.Extensions.Caching.SqlServer docs for .NET 10.0 APIs

# Microsoft.Extensions.Caching.SqlServer docs for .NET 10.0 APIs

## Description

This issue tracks the porting of documentation for 6 APIs in the `Microsoft.Extensions.Caching.SqlServer` namespace that were added in .NET 10.0.

## Instructions

Please follow the instructions in the main tracking issue (#120483) for documenting these APIs.

## Undocumented APIs

The following APIs need documentation:

### SqlServerCache

- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCache.#ctor(Microsoft.Extensions.Options.IOptions{Microsoft.Extensions.Caching.SqlServer.SqlServerCacheOptions})](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCache.xml)
- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCache.Microsoft#Extensions#Caching#Distributed#IBufferDistributedCache#Set(System.String,System.Buffers.ReadOnlySequence{System.Byte},Microsoft.Extensions.Caching.Distributed.DistributedCacheEntryOptions)](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCache.xml)
- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCache.Microsoft#Extensions#Caching#Distributed#IBufferDistributedCache#SetAsync(System.String,System.Buffers.ReadOnlySequence{System.Byte},Microsoft.Extensions.Caching.Distributed.DistributedCacheEntryOptions,System.Threading.CancellationToken)](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCache.xml)
- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCache.Microsoft#Extensions#Caching#Distributed#IBufferDistributedCache#TryGet(System.String,System.Buffers.IBufferWriter{System.Byte})](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCache.xml)
- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCache.Microsoft#Extensions#Caching#Distributed#IBufferDistributedCache#TryGetAsync(System.String,System.Buffers.IBufferWriter{System.Byte},System.Threading.CancellationToken)](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCache.xml)

### SqlServerCacheOptions

- [M:Microsoft.Extensions.Caching.SqlServer.SqlServerCacheOptions.#ctor](https://github.com/dotnet/dotnet-api-docs/blob/main/xml/Microsoft.Extensions.Caching.SqlServer/SqlServerCacheOptions.xml)

Total APIs to document: 6

Start with the instructions in the main tracking issue, #120483, then inspect the linked SqlServerCache.xml and SqlServerCacheOptions.xml files. Document the five listed SqlServerCache members and the SqlServerCacheOptions constructor for .NET 10.0; done means all six APIs listed here have documentation.
