build!: move the module to /v2

`go install github.com/Flagsmith/flagsmith-cli@latest` resolves v1.1.0 — the
npm-era tag, which contains no Go code — and fails with "does not contain
package". Tagging v2 does not fix it: a module at major 2 or higher must carry
the matching path suffix, and the +incompatible escape applies only to repos
without a go.mod, so v2 tags would simply be invalid for the old path and
@latest would stay on v1.1.0 forever.

The suffix is unavoidable if we tag v2 at all; the alternatives were releasing
the rewrite on the v1 line or dropping `go install` from the docs.

The README pins the beta tag rather than using @latest, which skips prereleases
when any release exists — v1.1.0 does. release-please keeps the pin current
through extra-files, same as the two installers.

`go install` names the binary after the module path, so it lands as
flagsmith-cli; the README says so.
