Docker image build step failing in CI due to node version incompatibility

[dcroote]

The docker image build step in CI has been failing e.g. since c43d981 due to a node version incompatibility with a package:

#5 22.58 error [email protected]: The engine "node" is incompatible with this module. Expected version "20 || >=22". Got "18.19.1"
#5 22.59 error Found incompatible module.

At the time, my quick Discord suggestion, which worked but was a hack, was below. The actual solution to this is to get Airnode working with Node.js 20, though that hasn't been straightforward (#1920)

Now yarn provides a way to ignore engines: --ignore-engines
To enable this for the Docker files being built, go into each of the following 3 Docker files:

./packages/airnode-node/docker/Dockerfile
./packages/airnode-deployer/docker/Dockerfile
./packages/airnode-admin/docker/Dockerfile

and add --ignore-engines to the end of the line in each starting with yarn global add (but add it before the && \ of course)

Then, run yarn docker:build:latest (this, importantly, rebuilds the packaging container first, which is necessary).
