cmd ref: double check example-get-started repo examples (tag names)

[jorgeorpinel]

The example-get-started repo changed from 2 tags to 12 at some point, but we didn't update all the examples in cmd ref (or any doc) that use them. More context in #933 (review)

Looks like I was wrong, tags are still here https://github.com/iterative/example-get-started/releases?after=1-initialize . And example get started and all example should use them where appropriate.

My bad. I thought they were gone because they don't come up in page 1 of https://github.com/iterative/example-get-started/tags
