[#498] Implement a workflow that triggers deployment to dev when a …

…tag is created (from a specific pattern)

The existing GitHub workflow has been modified to introduce automated
triggering for deployments to the `dev` branch on the development server
upon the creation of a new tag that matches the pattern
`refs/tags/dev-`. The workflow can now distinguish between automated
activation triggered by specific tag creation and manual activation by
the user. By adding a new workflow configuration file,
`.github/workflows/deploy-dev-from-tag.yml`, the automation process for
deployments has been enhanced to react promptly to tag creation events
following the specified pattern.

Changes:
- Created a new GitHub workflow configuration file,
  `deploy-dev-from-tag.yml`, to facilitate automated deployment
  activation based on tag creation matching the predefined pattern
  `refs/tags/dev-`.
- Configured the workflow to differentiate between automated triggering
  upon tag creation and manual activation.
- Updated the workflow to respond effectively to tag creation events
  following the specified pattern, ensuring seamless deployment
  processes and providing the flexibility of manual activation as
  required.
