mardizzone/pos-944: snyk and govuln integration

[marcello33]

Description

This PR integrates snyk security CI into bor GH pipeline.
It executes snyk vulnerabilities check and snyk static code analysis and publish the results into the relative action.
Licenses check has been removed from snyk UI as ours is a open source organization.
Also, it solves some high security issues (not related to licenses).

Furthermore it integrates govuln check as additional step in the tests (if the OS is ubuntu), to check if the code has any golang related vulnerabilities.
