There's this issue in vscode's eslint plugin where it picks up our .eslintrc.js file and the .eslintrc.js file specifies tsconfig-lint.json as the ts config file, but vscode uses tsconfig.json anyway.

tsconfig.json ignores tests as an optimisation and tsconfig-lint.json then overrides that.

One way to get around this is to "invert" it of sorts: have tsconfig.json check everything including tests and have a tsconfig-build.json that overrides the included files to skip tests. Then when we compile we'd use tsconfig-build.json.

Then we should see all the errors in our tests show up in vscode.

Reasoning: We accidentally didn't typecheck a bunch of packages. One of those (at the time of writing) is packages/connection-form. Once I turned on typecheck there were 131 errors in 18 files. But vscode wouldn't highlight those errors which makes it a pain to find and fix them all because you can only see them on the CLI.

And that's just one package we skipped..
