Use shared SPDX action

[SebastianSchildt]

This iuses the shared SPDX action in the new Orga. Should not change anyhting functionality wise.

I am however not sure if deleting the action itself has neagative side effects in case it is used elsewhere. If other repos refer to a tag, no issue, if they refer to no reference or master it needs further PRs in the other Repos. Any idea @erikbosch ?

Don't you need to change https://github.com/eclipse/kuksa.val/blob/master/.github/workflows/check_license.yaml so that it uses the action from the new location (i.e. https://github.com/eclipse-kuksa/kuksa-actions)

Yes, it is true that other workflows in other repos might need to be changed (like https://github.com/eclipse/kuksa.val.feeders/blob/main/.github/workflows/check_license.yaml) but that is wanted. Using latest master/main is always risky :-)

I need, I did, I didn't push, hopefully fixed now

You need to remove trailing whitespaces on line 10 as well
