git tags are not consistent about opensm

[hnrose]

I noticed that the latest git tag is 3.3.21
This is not consistent with the other git tags in this repo, like opensm-3.3.20

When switching over to github, there was issue with labels in terms of release so the opensm- needed to be dropped. See ##1

I wrote a script that relies on the convention that all tags in the opensm repo starts with opensm- to fetch the correct version.

Can you update your script based on the change in the tag naming scheme ?

Would you be kind enough to add the following git tag: opensm-3.3.21
Thank you.

Thank you @hnrose for your explanation.

I will update my script base on the new naming scheme
