corrected go version

[jdob]

Not entirely sure what happened, but the project just stopped working on my Mac overnight with the following:

$ go mod tidy
go: downloading go1.22 (darwin/arm64)
go: download go1.22 for darwin/arm64: toolchain not available

I looked around and found [1] which talks about the issue. The fix works and I don't think there are any other implications in changing this.

Closed out; while this probably wouldn't cause an issue, my local go was behind. When I updated that it worked fine as is, and it's late in the dev cycle to dork with any of this if we don't need to.
