Including the minor version number seems unnecessary. Is it something that only started happening for Go 1.22?

Including the minor version number seems unnecessary. Is it something that only started happening for Go 1.22?

I agree. Apparently beginning with release 1.21, the first release included a minor version number (1.21.0 as opposed to just 1.20), which is partially what leads to this issue. After a bit more research, this has been fixed in go, but only available as of 1.21.11 and 1.22.4.

Given that, it's likely fine not merging this as the impact is low. If we do merge it in, it looks like most folks specify 1.22.0 as opposed to the minor release version as the .0 is the first toolchain of the language version (and what the above patch will do if it's not present as well).
