Fix publish version output and redundant country-code pattern

The publish workflow used GitVersion's nuGetVersionV2 output, which was
removed in GitVersion 6, so -p:Version came through empty and the build
failed on newer SDKs (GenerateDepsFile missing AssemblyVersion). Switch to
the semVer output for both build and pack.

Also fix Alpha2CountryCodeAttribute: 'is not > A and < Z' parsed as
'(<= A) and (< Z)' (CS9336 redundant pattern) and wrongly excluded the
letters A and Z. Use 'is not (>= A and <= Z)' to reject only non-uppercase
characters.
