Still errors for module and exports, and require's type is now incorreclty 'any'; I broke module resolution somehow. Needs investigation.
Everything passes the tests but the code can be improved

we shoudl change all other uses in the checker for isRequireCall to use the symbol identity check instead.

But you only get requireSymbol when @types/node (or other declaration) is not present. See the rest of isCommonJsRequire for the verification that's needed on declarations from things like @types/node.

Oops. Thanks for catching that.
It wasn't doing anything anyway.

Fixes #21933, although I still intend to add a quick fix for Typescript that runs
npm install @types/node, and a quick fix for require("fs") that does the same thing. (That second quick fix would apply to JS and TS.)Note that I removed declarations for
require/module/exportsfrom a couple of the JS tests. There are plenty that still have their own declarations, which tests the rest of the code inisCommonJsRequireafter line 18772.
