splunkclient-go does not build or run tests, cannot be imported

[andrewwdye]

Describe the issue
The go:build directives in splunkclient-go prevent building in recent versions of go. Attempts to import github.com/signalfx/splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go/transport per the example fail with undefined errors.

Looks like this attempt to require >= go1.17 does not work as expected and should instead by a single directive like //go:build go1.17 to indicate min version.

Steps to reproduce the issue:

❯ git clone https://github.com/signalfx/splunk-otel-go.git

❯ cd splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go

❯ go test ./... -v
?   	github.com/signalfx/splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go	[no test files]
?   	github.com/signalfx/splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go/internal/config	[no test files]
?   	github.com/signalfx/splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go/option	[no test files]
?   	github.com/signalfx/splunk-otel-go/instrumentation/k8s.io/client-go/splunkclient-go/transport	[no test files]

❯ go version
go version go1.21.3 darwin/arm64

Attempted solutions and workarounds
Simply replacing

//go:build !(go1.1 || go1.2 || go1.3 || go1.4 || go1.5 || go1.6 || go1.7 || go1.8 || go1.9 || go1.10 || go1.11 || go1.12 || go1.13 || go1.14 || go1.15 || go1.16)
// +build !go1.1,!go1.2,!go1.3,!go1.4,!go1.5,!go1.6,!go1.7,!go1.8,!go1.9,!go1.10,!go1.11,!go1.12,!go1.13,!go1.14,!go1.15,!go1.16

with

//go:build go1.17
// +build go1.17

seems to address the problem

Expected behavior
Existing tests run
