Error when generating specs using Go 1.21.x

[dannyskoog]

Problem statement

When trying to generate specs in a codebase with a go directive like go 1.21.5, the following error is returned:

err: exit status 1: stderr: go: errors parsing go.mod:
/go/src/github.com/voiapp/rms-gateway/go.mod:3: invalid go version '1.21.5': must match format 1.23

Steps to reproduce

Presumably whatever specs generation command. But in my case:
docker run --rm -v /Users/dannyskoog/GIT/go/src/rms-gateway:/go/src/github.com/voiapp/rms-gateway -w /go/src/github.com/voiapp/rms-gateway quay.io/goswagger/swagger:v0.30.5 generate spec --exclude-deps -i ./api/swagger-definitions.yaml -o ./api/swagger.json

Environment

swagger version: 0.30.5
go version: 1.21.5
OS: Ubuntu 22.04.3

I realised that the quay.io/goswagger/swagger:master Docker image seems to work.

The docs, although, implies (implicitly) that the latest tag should be used (see https://goswagger.io/install.html#docker-image-). Is that intentional, given the fact that the latest tag hasn't been updated in 7 months?

Having a more recent tag would also help with Go 1.22: #3070 (different problem, but I guess the tag would solve both issues)
