Unable to install httpfs extension on windows_arm64 laptop (i.e. Surface Laptop)

This is the message received -
```
D INSTALL httpfs;
HTTP Error:
Failed to download extension "httpfs" at URL "http://extensions.duckdb.org/v1.4.2/windows_arm64/httpfs.duckdb_extension.gz" (HTTP 404)
Extension "httpfs" is an existing extension.
```

When I use a browser, I am able to download the windows_amd64 version, but not the windows_arm64 version.

Start by reproducing `INSTALL httpfs;` on Windows ARM64 and inspect the failing v1.4.2 URL for the missing `windows_arm64/httpfs.duckdb_extension.gz` artifact. Compare it with the downloadable Windows AMD64 extension; done means the ARM64 extension can be installed successfully from the expected URL.
