Updated dependency

bump elixir from 1.18.3-otp-27-alpine to 1.18-otp-27-alpine in the dependabot-patch-and-minor-docker group

What you expected to see, versus what you actually saw

We are using the elixir Docker image at elixir:1.18.3-otp-27-alpine for one of our images, but Docker keeps opening incorrect upgrades which change the version constraint to be less specific than we have requested. (An example from one repo has been provided, but this is happening across multiple repos.)
