Version bumps start PRs instead of committing directly

[HollowMan6]

This PR change the version bumping workflow into the follows to resolve

• Keep kubescape github-action workflow up to date #38 (comment)

Now the workflow gets triggered by committing into main branch or manually.

• If any of the new release in the upstream is found, we start a new PR and get the docker image version bumped.
• If the image version is bumped and no corresponding version tag is found in this repository, the workflow makes a new release for this action.

@dwertent As a follow up of this PR, would you please set this repository to allow GitHub Actions to create and approve pull requests? https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository#preventing-github-actions-from-creating-or-approving-pull-requests

The workflow is failing and it shows that "Error: GitHub Actions is not permitted to create or approve pull requests." https://github.com/kubescape/github-action/actions/runs/4940978328/jobs/8833162723

I've updated the org and the repo to allow creating/approving pull requests from an action.

The commit doesn't have the DCO applied, so I fixed that in the file.

#56
Has created a valid PR.

I am in favour of making this PR auto-merge. @TRohit20 can help with that :)

[TRohit20]

Yes, I reckon the action can be triggered with every release to check the version, update automatically if any different. Wdyt? @craigbox

I can work on automating this.
