ubuntu-latest
is a moving target, it now points to 22 which has little support for older OTP versions. Arguably our matrix is a little too conservative with retaining older versions and we're also updating our matrix but I think OTP 23 support is still reasonable and anyway I'd rather pin to a specific release.
