feat(workflows-chainloop): Consolidates robot accounts into API token

[javirln]

This patch drops support for Chainloop Robot Accounts in favor of API Tokens by using the env variable CHAINLOOP_TOKEN. It additionally performs the following changes:

• Bump version of Chainloop CLI to ensure latest compatibility
• Bump reusable workflows to their latest version available on Chainloop's labs

[javirln]

Reusable workflows needs to be updates in order to accept an API Token as input through CHAINLOOP_TOKEN.

Refs chainloop-dev/labs#22

[javirln]

Reusable workflows need to allow to pass down the workflow name required by API tokens: chainloop-dev/labs#24

[javirln]

This PR needs changes on this merged one #874 to be deployed so the remote state can work properly using API tokens.

[javirln]

Scorecard workflow is working with the changes regarding the attestation however, it's failing due failure on the generation of reports: https://github.com/chainloop-dev/chainloop/actions/runs/9381594534/job/25831213115

I haven't touch anything regarding that part, only bump the version of the associated reusable workflows.

[javirln]

The issue is that the chainloop_push reusable workflow is expecting a file that we are not generating anymore. We are adding a condition there.
