Add MSVC dependency to installation page

[szarnyasg]

Raised by @Giorgi on Discord:

https://duckdb.org/docs/api/python/known_issues#error-when-importing-the-duckdb-python-package-on-windows the Python on Windows [...] requires Microsoft Visual C++ Redistributable package.

The dotnet library users on Windows also need to install it

I think it will be better to move that note (or copy) from Python package docs to the DuckDB Installation page when Windows is selected as a Platform.

@szarnyasg your pr hasn't quite fixed the issue here, so I've reopened it

[szarnyasg]

@Mause can you please elaborate? We don't have a documentation / installation page on the .NET driver so I cannot include this information there. I'd like to leave the error message in the known Python issues page as people end up there from search engines.

The library is required on windows regardless of binding I believe

[Giorgi]

The MSVC dependency isn't Python specific, it's Windows specific, so I think the note should also be present on the DuckDB Installation page. If someone uses Java library on Windows they need MSVS too (that's my understanding)

Thanks both!
