move dt tests to yaml in this repo

[iisaduan]

To make a new pipeline to run the dt tests with tsgo, I need to host the yaml somewhere. I'm going to be testing this in a different branch, but I need to push to main in order to create a new pipeline (the file needs to exist in main). This yaml file is just the existing DT pipeline converted to yaml, the only change is that it also installs go.

I don't know how we plan to do DT, the toolchain there strongly relies on the API and ts-eslint which we don't have.

hmmmm, i can't change the resource for the existing dt test pipeline without removing the original ts repo as a resource. It's not been triggered often recently, so I guess I could do it like that? Open to other suggestions as well

It looks like i'm unable to do a lot of potentially possible things there because "classic pipelines are disabled for this project/org"

The pipeline is not the real problem here; I don't mind moving the yaml. I'm saying that running the DT tests themselves is not currently feasible, because dtslint does not work with tsgo.
