replace strings.Split(N) for strings.Cut() or alternatives
Go 1.18 and up now provides a strings.Cut() which is better suited for
splitting key/value pairs (and similar constructs), and performs better:

```go
func BenchmarkSplit(b *testing.B) {
	b.ReportAllocs()
	data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
	for i := 0; i < b.N; i++ {
		for _, s := range data {
			_ = strings.SplitN(s, "=", 2)[0]
		}
	}
}

func BenchmarkCut(b *testing.B) {
	b.ReportAllocs()
	data := []string{"12hello=world", "12hello=", "12=hello", "12hello"}
	for i := 0; i < b.N; i++ {
		for _, s := range data {
			_, _, _ = strings.Cut(s, "=")
		}
	}
}
```

    BenchmarkSplit
    BenchmarkSplit-10    	 8244206	       128.0 ns/op	     128 B/op	       4 allocs/op
    BenchmarkCut
    BenchmarkCut-10      	54411998	        21.80 ns/op	       0 B/op	       0 allocs/op

While looking at occurrences of `strings.Split()`, I also updated some for alternatives,
or added some constraints;

- for cases where an specific number of items is expected, I used `strings.SplitN()`
  with a suitable limit. This prevents (theoretical) unlimited splits.
- in some cases it we were using `strings.Split()`, but _actually_ were trying to match
  a prefix; for those I replaced the code to just match (and/or strip) the prefix.

format code with gofumpt
gofumpt (https://github.com/mvdan/gofumpt) provides a supserset of `gofmt` / `go fmt`,
and addresses various formatting issues that linters may be checking for.

We can consider enabling the `gofumpt` linter to verify the formatting in CI, although
not every developer may have it installed, so for now this runs it once to get formatting
in shape.

go.mod: change imports to github.com/distribution/distribution/v3
Go 1.13 and up enforce import paths to be versioned if a project
contains a go.mod and has released v2 or up.

The current v2.x branches (and releases) do not yet have a go.mod,
and therefore are still allowed to be imported with a non-versioned
import path (go modules add a `+incompatible` annotation in that case).

However, now that this project has a `go.mod` file, incompatible
import paths will not be accepted by go modules, and attempting
to use code from this repository will fail.

This patch uses `v3` for the import-paths (not `v2`), because changing
import paths itself is a breaking change, which means that  the
next release should increment the "major" version to comply with
SemVer (as go modules dictate).

91f268e5a5 Downgrade token auth JWT logging from error to info
The token auth package logs JWT validation and verification failures at
the `error` level.  But from the server's perspective, these aren't
errors.  They're the expected response to bad input.  Logging them at
the `info` level better reflects that distinction.

Add leeway to JWT nbf and exp checking
Adds a constant leeway (60 seconds) to the nbf and exp claim check to
account for clock skew between the registry servers and the
authentication server that generated the JWT.

The leeway of 60 seconds is a bit arbitrary but based on the RFC
recommendation and hub.docker.com logs/metrics where we don't see
drifts of more than a second on our servers running ntpd.

I didn't attempt to make the leeway configurable as it would add extra
complexity to the PR and I am not sure how Distribution prefer to
handle runtime flags like that.

Also, I am simplifying the exp and nbf check for readability as the
previous `NOT (A AND B)` with cmp operators was not very friendly.
