Build/Test Tools: Simplify the @global type pattern in GlobalDocBlockVisitor.

`(\S+(?:\s*\|\s*\S+)*)` was over-engineered: it explicitly handled spaced unions like `WP_User | WP_Error` but failed to capture types with internal whitespace such as generics (`array<string, int>`).

`(\S.*?)` — anchored on a non-whitespace start and reluctantly matching up to the next `\s+\$\w+` — is functionally equivalent for every type form the alternation already handled, while also correctly capturing types that contain spaces. Whitespace is still collapsed before storing the type. Net effect: 12 additional `@global` tags are now recognized in the codebase.
