chore: allow relative imports with ts file extension

[nicknovitski]

Why

ESM requires relative imports to have file endings. New versions of typescript finally allow us to write source files with imports ending in .ts and get built files with imports ending in .js. If you run node --experimental-transform-types on a file, it will treat the import paths as they're written, so typescript source files need to be importing their typescript siblings.

With this enabled, we can run node with strip- or transform-types on the source files, and run tsc to get correctly built output with .js imports.

How

Just added the setting. See other PRs in the stack for changes which depend on this.

Test Plan

No changes to source.
