Glad to see we finally merged these RVMs! Thanks @mehrdadh for doing this work.

+## Versioning
+We use semantic versioning as it is recommended by [Vagrant](https://www.vagrantup.com/docs/boxes/versioning). We use `X.Y.Z` version where we maintain the same major version `X` it has minor changes and newer version is still compatible with older versions and we increase minor version `Y`. However, We increase the major version `X` when new RVM is not compatible with older onces. Updating Zephyr SDK is considered a major change and it requires incrementing major version `X`.

Do we use Z in X.Y.Z? If we don't (as I don't think we do) we should mention that it is rarely used.

If __file__ isn't defined for some reason, I think the previous code would throw an error anyway.

because it is already added in first line

it's not terrible to do this explicitly in the script actually--the first line is only ran when you directly invoke it as a command rather than just via bash path/to/script.sh

Thanks for the changes! LGTM.

While testing this PR on physical hardware, me and @mehrdadh ran into #12033. However, I'm confident that the test failure is unrelated to the changes in this PR, so I'm cool with this PR being merged.
