Nathan van Doorn b63dfb7ad4 Rename version to version.txt
<version> is a standard header with C++20 which could cause issues if a library checks it exists then imports it

Because we have the root of this repo in the include path, it'd see that <version> exists (with, e.g., __has_include), and then try to include it as a header

But because it's just a file that says 0.1, this would fail

This happens with libpqxx 7
