FOSSA CI workflow is incomplete

[aniketchawardol]

The FOSSA workflow (.github/workflows/fossa.yml) it is not doing anything at this state. It checks out the repo and runs go version, but the FOSSA scan step is missing.
the scan step was added in PR #42 but then removed 8 days later in commit 5ebeb7d (Aug 10, 2020) . Since then the workflow is empty.

Also, the workflow sets up Go 1.14.x, which I don't think is needed here since this is a Hugo site with no Go code.

Should this be:
Fixed : restore the FOSSA scan using a repo secret for the API key and bump the outdated action versions (checkout v2→ v4 etc.)
Or just removed if FOSSA scanning isn't being used anymore?

Since this is just a Hugo docs site with no real dependencies, FOSSA scanning probably isn't needed here, it's already running on the main volcano-sh/volcano repo where it actually matters.
