[WebIDE] Remove .cdn.web-ide.gitlab-static.net cloudflare deployment

MR: chore: Remove cloudflare worker deployment (!126 - merged)

Problem to solve

Now that we've successfully moved the .cdn.web-ide.gitlab-static.net cloudflare worker to the gitlab-org/gitlab-web-ide project, we have a duplicated Cloudflare worker implementation that we have to remove from the gitlab-org/gitlab-web-ide-vscode-fork repository.

Solution

Remove the duplicated implementation of the .cdn.web-ide.gitlab-static.net cloudflare worker from the gitlab-org/gitlab-web-ide-vscode-fork project and update the CI pipeline so it doesn't try to deploy this worker anymore.

Acceptance criteria

• Remove the following CI jobs:
  • .deploy-cloudflare-worker
  • deploy-cloudflare-worker-staging
  • deploy-cloudflare-worker-production
• Remove the directory https://gitlab.com/gitlab-org/gitlab-web-ide-vscode-fork/-/tree/main/cloudflare?ref_type=heads from the gitlab-org/gitlab-web-ide-vscode-fork repository.
