Backport: Fix a potential data race on a global variable

[pior]

Re-apply the same fix as #2171 on v1.30.1

[dnwe]

@pior I'm not sure I understand? you've branched from the v1.30.1 tag and added the version.go fix that was previously merged to main — I guess this branch is for your own usage?

I'm not sure what the pull request is intended for though — were you hoping that we would make a 1.30.2 based on your branch?

Maybe?
Since 1.30.1 is the last stable version (at least for us?), and it has this datarace bug, I think that would make sense until 1.33 is released.

@pior apologies I didn't get back to you on this — I have now pushed out a release for 1.33, if you could give that a test and see if it resolves the issues you were seeing post-v1.30.1 that would be great
