Restart pod on Podman when related information is changed in Devfile

User Story

As a user running odo against Podman, I want changes to my Devfile to be detected and applied, So that I can continuously iterate on my project without having to restart odo dev manually.

Restarting odo dev manually every time I edit something in the Devfile can be annoying and time-consuming.

Currently, it detects any changes to the Devfile and warns users that odo dev needs to be restarted (see #6336). Even changes that would not affect the running Pod (like changes to the build or run commands) are ignored.

Acceptance Criteria

• [ ] It should recreate the Pod on Podman if there are changes in the Devfile that would modify the Pod spec (e.g., changes in the container component, ...)
• [ ] It should not recreate the Pod on Podman if there are changes in the Devfile that would not modify the Pod spec (e.g., changes to the run command only)
• [ ] Similarly to how odo dev works against a cluster, it should notify users of the current Pod state
• [ ] Similarly to how odo dev works against a cluster, external factors that might affect the running Pod should also be handled by recreating the Pod if needed (but that can be a separate issue)
• For now, it should just recreate the Pod on Podman if there any changes in the Devfile
• Update documentation: remove this point from the "Podman Support limitations" page
