Specify library name and version: libvault/0.48.0

This is also a good place to share with all of us why you are submitting this PR (specially if it is a new addition to ConanCenter): is it a dependency of other libraries you want to package? Are you the author of the library? Thanks!

Not the author, but I wish to use this library in my existing Conan project.

@uilianries @SSE4 could I please get some help here if you get a chance? It looks like CI is using a current version of clang but I am still getting fatal error: 'filesystem' file not found #include <filesystem>

Compiling with filesystem and clang 11 on godbolt works though: https://godbolt.org/z/v9b389M5a

TLDR: you can exclude clang + libstdc++ for now
