go install instructions are outdated

[glensc]

$ go version
go version go1.18.3 darwin/amd64
$ go get -u github.com/joseluisq/enve
go: go.mod file not found in current directory or any parent directory.
        'go get' is no longer supported outside a module.
        To build and install a command, use 'go install' with a version,
        like 'go install example.com/cmd@latest'
        For more information, see https://golang.org/doc/go-get-install-deprecation
        or run 'go help get' or 'go help install'.

this works now:

$ go install github.com/joseluisq/enve@latest
go: downloading github.com/joseluisq/enve v1.4.0
go: downloading github.com/joseluisq/cline v0.1.0
go: downloading github.com/joho/godotenv v1.4.0

Good catch!
Feel free to fix that with a PR if you want.
