Dash check runs in the "wrong place" in CI for Rust builds

[SebastianSchildt]

For databroker(-cli) we

• create an input file for Dash and a BOM (createbom)
• Run the dash tool agains the input file and archive outcomes

This currently is done in the "Lint" step, which seems wrong (was likely done to "recylce" the builder").

See https://github.com/eclipse/kuksa.val/actions/runs/6328141013/job/17246390201

Way forward seems

• do not do the Createbom in the "lint" step but have something in buold or seperate
• The DASH tool check (e.g. processing a Dash file and archiving the outputs) should be spun out in a separate action probably in the shared actions repository, as this is the same no matter we do it for pyton, rust, Kotlin etc....
