Can't `go install` the binary

[liamdawson]

When attempting to build an image that uses this utility, I ran into an error when trying to install it via go install:

$ docker run --rm -it golang:1.18-alpine3.15 /bin/sh

$ go install github.com/adrienkohlbecker/[email protected]
go: downloading github.com/adrienkohlbecker/traefik-auth-cloudflare v0.0.0-20210816090815-389b9d8fbfa4
go: github.com/adrienkohlbecker/[email protected]: github.com/adrienkohlbecker/[email protected]: parsing go.mod:
        module declares its path as: github.com/ciffelia/traefik-auth-cloudflare
                but was required as: github.com/adrienkohlbecker/traefik-auth-cloudflare

I think #8 broke it at https://github.com/adrienkohlbecker/traefik-auth-cloudflare/pull/8/files#diff-33ef32bf6c23acb95f5902d7097b7a1d5128ca061167ec0716715b0b9eeaa5f6R1
