Remove the license entry to each algorithm .yam file

[toscalix]

Background

Due to my limitations maganing git, at some point I introduced back again the license entry to each license file, which at the Cryptography Group we agreed is was overkill, given the assigned license.

Rationale

We need to revert this mistake.

Description

The .yaml files should not have any license entry because the license is CC0 for the entire repo. It is overkill

Actions

• Identify the affected algorithms
• Create a single PR removing the license entry from all the affected algorithms

DoD

• Link to the PR
• Link to one of the affected algorithms without the license entry:

It would be good to confirm this. Check the the SPDX license list
