README: list only template repos that exist (closes #153)

`template-app-js` and `template-app-python` do not exist on
git.eeqj.de. The Template Repos section now lists `template-app-go` and
`go-template-repo`, the two template repos kept in step with this repo.
The closing sentence restated the opening one and is gone.

Model: opus-5-5
