feat: enhance management of custom docker images

[leovct]

Description

Currently, we manage three custom Docker images for deploying the CDK stack: one housing various zkevm contracts (each fork tagged separately), another adapting the bridge UI to accommodate relative URLs, and a third for applying workloads.

The aim is to:

• [x] 1. Streamline the organization of our Dockerfiles and forks.
• [x] 2. Establish a daily or weekly cron job for building and pushing these images.
• [ ] 3. Transition the hosting of these images from DockerHub to GCR. => For the moment, images are still hosted on the Docker Hub under my username. That's fine for now. https://hub.docker.com/u/leovct

Other

• Fix npm install random fails with ECONNRESET and ETIMEDOUT by upgrading npm to a version higher or equal to 10.5.1 (see the fix: https://github.com/npm/cli/pull/7324)
• Fix hadolint check in CI.
• Lint some Dockerfile files.

Test

I enabled the CI to run on this PR. I'll remove it once we've tested that we can build and successfully send images to our GCR.
