Fix building Docker images locally

[Siegrift]

See the steps to reproducible the issue here. There is the following error:

error Couldn't find any versions for "@api3/airnode-admin" that matches "snapshot-local"

This has been briefly discussed internally here, but so far without resolution.

Ah, it turns out this very non-intuitive error is a result of not having a changeset affect a package, which in turns results in packages not being published to the local npm registry, and therefore airnode-admin can't be found. I've run into this myself before: #1585 (comment) and it happens after every fresh release (since all changesets are cleared) e.g. for v0.14.2 here:

#5 [2/3] RUN npm set registry http://172.17.0.3:4873/ &&     yarn global add @api3/airnode-admin@snapshot-3b81fd6b4300b7a13e288e8dda133ad1fe3e0d17 &&     ln -s /usr/local/share/.config/yarn/global/node_modules/@api3/airnode-admin/dist /app &&     adduser -h /app -s /bin/false -S -D -H airnode-admin
#5 0.771 yarn global v1.22.19
#5 0.827 [1/4] Resolving packages...
#5 0.885 error Couldn't find any versions for "@api3/airnode-admin" that matches "snapshot-3b81fd6b4[30](https://github.com/api3dao/airnode/actions/runs/9753460312/job/26918839398#step:7:31)0b7a13e288e8dda133ad1fe3e0d17"

The solution is to run yarn changeset, add at least one patch change (placeholder message is fine), and commit the resulting file along with the source code changes and then proceed with yarn docker:build:local.
