Move go.mod to Go 1.17

fixes tektoncd#4725 (sorta)

Since tektoncd#4712, we've actually required Go 1.17 to build, but
`go.mod` still was set to `go 1.16`. I noticed this because I have a hack locally that sets the Go
version in the CLI based on what's in `go.mod`, and then couldn't do `go run hack/spec-gen/main.go`.
Given that our CI is all using 1.17 and we require 1.17 to compile/build, we might as well update
`go.mod` as well.

Note that there was one quirk moving to 1.17 - running `go mod tidy` initially got:

```
github.com/tektoncd/pipeline/pkg/apis/config imports
	knative.dev/pkg/metrics imports
	contrib.go.opencensus.io/exporter/prometheus imports
	github.com/prometheus/client_golang/prometheus imports
	github.com/cespare/xxhash/v2 loaded from github.com/cespare/xxhash/[email protected],
	but go 1.16 would select v2.1.2

To upgrade to the versions selected by go 1.16:
	go mod tidy -go=1.16 && go mod tidy -go=1.17
If reproducibility with go 1.16 is not needed:
	go mod tidy -compat=1.17
For other options, see:
	https://golang.org/doc/modules/pruning
```

I took a look, and we already had `github.com/cespare/xxhash/[email protected]` in `go.sum`, so I decided
that we should do the `go mod tidy -go=1.16 && go mod tidy -go=1.17` approach rather than the
`go mod tidy -compat=1.17` one, to keep the current version we appear to be indirectly referencing.
Also, this means that we don't need to change `hack/update-deps.sh` to have `go mod tidy -compat=1.17`,
because the `go.mod` is now fully 1.17 compatible while having the `xxhash` version we would have
expected.
