Cannot parse `import {type A, type B} from ...` about flowgen

[stackptr]

Using the TypeScript AST Viewer shows that in recent versions of typescript (since at least 4.5.5), the type keyword in comma-separated imports does not show up as an ImportSpecifier within NamedImports. However, in the version closest to what is used by flowgen, the AST contains an ImportSpecifier for both type and the named import. The only way I see to distinguish the two is by checking the name.originalKeywordKind, which is ts.SyntaxKind.TypeKeyword. Unfortunately, updating nodes/import.ts to simply filter out these nodes does not do the job... the type keyword needs to be preserved but not treated as an identifier itself.
