fix extension load error message grammar

[softprops]

I experienced some unusual grammar when trying to load an extension that didn't line up with the running DuckDB. Below is the before and after of the messaging change

before

Invalid Input Error: Extension "zig-out/lib/quack.duckdb_extension" do not have metadata compatible with DuckDB loading it (version v0.10.2, platform osx_arm64)

after

Invalid Input Error: Extension "zig-out/lib/quack.duckdb_extension" does not have metadata compatible with the DuckDB loading it (version v0.10.2, platform osx_arm64)
