This change is required to address high-severity vulnerabilities in golang.org/x/crypto.

We only officially support the latest two versions, but is there any reason to not test the older version as well until if starts failing?

[nodivbyzero]

@deankarn I'm just trying to understand the reasoning - why test the older version if it's no longer officially supported?
Are we planning to address any breaking issues if tests start failing on that version?

@deankarn
I've added a new workflow that triggers on pushes to the master branch and runs tests using Go versions 1.21 through 1.24.
