Toolkit does not recognize `.devfile.yml` files

[AgentK9]

E.g. without the a in yaml.

Looks like the offending line is here: https://github.com/redhat-developer/vscode-openshift-tools/blob/9aa1bc44bb45c54155beaa713030ce18cc046c1d/src/util/workspace.ts#L130

However there could be other parts that my cursory examination did not find.

@datho7561 can you please look into this and we should update our use case based on the file extension.

We don't detect devfile.yml or .devfile.yml, since odo don't detect those either.

We should narrow the scope of the file watchers, since this will also match not-actually-a-devfile.yaml, which also isn't recognized by odo. I'll try to handle this aspect as a part of #3120
