Starting a new workspace from a RAW devfile URL doesn't support URL parameter for the devfile file name

[vinokurig]

Describe the bug

We can start a new workspace from a RAW devfile URL. In case if the devfile file name differs from the conventional (devfile.yaml or .devfile.yaml) We have URL parameter for the devfile file name to be able to specify the devfile filename. Currently workspace fails to start from the Raw devfile URL with unconventional yaml name, either with the ?df=<filename>.yaml parameter.

Che version

7.71@latest

Steps to reproduce

1. Create a GitHub gist named test.devfile with a simple devfile content. Copy the Raw URL of the gist.
2. Start a workspace with the RAW devfile URL

See: workspace fails to start.

IMO, ?df=<filename>.yaml parameter does not make sense for raw URLs. Wondering what break it in 3.7 if in 3.6 looks like any filename for raw URLs worked

[vinokurig]

I assume this worked before the eclipse-che/che-server#519 PR. And before the PR it worked only for defiles by the GitHub RAW file content.

IMO, ?df=.yaml parameter does not make sense for raw URLs.

Do you think we should ignore the yaml file name for the RAW devfile URL approach?

[l0rd]

@vinokurig if the user provides a link to the raw devfile then the name of the file is included in the link. We should ignore the df URL parameter.
