build: convert eslint-remote-tester config to typescript (#533)

* git mv

* build: convert eslint-remote-tester config to typescript

Supporting the larger typescript migration, this change migrates the config for `eslint-remote-tester` to typescript, which will be necessary to run our plugin from source, once it's typescript.

* Bump version of eslint-remote-tester to pick up bug fix
