Update tools dep due to panic

[daved]

After running into:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
        panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x62e5af]

Which showed:

golang.org/x/tools/go/packages.(*loader).loadRecursive(0x0?, 0x0?)
        /home/daved/code/pkg/mod/golang.org/x/[email protected]/go/packages/packages.go:787 +0x3b

I only spent enough time debugging to confirm that the calling code was encountering this issue due to the golang.org/x/tools dep. After updating, the issue is gone. This does bump the Go version to 1.22.0. In February, 1.22.0 will no longer be supported, but it's an improvement over the previous 1.16 value. The build has only been confirmed using Linux.
