[axenteoctavian]

Reasoning behind the pull request

• Each new push starts a new actions without closing current running actions

Proposed changes

• Added concurrency block that groups runs by workflow name + branch ref and cancels any in-progress run when a new push arrives on the same branch

Testing procedure

Pre-requisites

Based on the Contributing Guidelines the PR author and the reviewers must check the following requirements are met:

• if this is a larger feature that probably needs more than one PR, is there a feat branch created?
• if this is a feat branch merging, do all satellite projects have a proper tag inside go.mod?
