`go install` errors

[drboone]

Doing go install github.com/barnybug/cli53/cmd/cli53@latest produces two errors:

go: github.com/barnybug/cli53/cmd/cli53@latest (in github.com/barnybug/[email protected]): go.mod:3: invalid go version '1.23.0': must match format 1.23
go.mod:5: unknown directive: toolchain

Apparently the trailing .0 is invalid? Not sure what the toolchain error is about. This is apparently a known problem:

Your version of Go is probably too old; the toolchain directive was introduced in Go 1.21.
